Abstract:

Radical chemistry is one of the most important methods used in modern polymer science and industry. Over the past century, new knowledge on radical chemistry has both promoted and been generated from the emergence of polymer synthesis and modification techniques. In this review, we discuss radical chemistry in polymer science from four interconnected aspects. We begin with radical polymerization, the most employed technique for industrial production of polymeric materials, and other polymer synthesis involving a radical process. Post-polymerization modification, including polymer crosslinking and polymer surface modification, is the key process that introduces functionality and practicality to polymeric materials. Radical depolymerization, an efficient approach to destroy polymers, finds applications in two distinct fields, semiconductor industry and environmental protection. Polymer chemistry has largely diverged from organic chemistry with the fine division of modern science but polymer chemists constantly acquire new inspirations from organic chemists. Dialogues on radical chemistry between the two communities will deepen the understanding of the two fields and benefit the humanity.

Abstract:

This review deals with two overlapping issues, namely polymer chemistry and deep eutectic solvents (DESs). With regard to polymers, specific aspects of synthetic polymers, polymerization processes producing such polymers, and natural cellulose-based nanopolymers are evaluated. As for DESs, their compliance with green chemistry requirements, their basic properties and involvement in polymer chemistry are discussed. In addition to reviewing the state-of-the-art for selected kinds of polymers, the paper reveals further possibilities in the employment of DESs in polymer chemistry. As an example, the significance of DES polarity and polymer polarity to control polymerization processes, modify polymer properties, and synthesize polymers with a specific structure and behavior, is emphasized.

Abstract:

Click chemistry refers to the type of chemical reactions that occur between specific pairs of reagents, taking place under mild conditions with high stereoselectivity. These characteristics help chemists to construct very complex molecules in a relatively easy, quick, and precise manner. Polymers are widely used in daily life which are composed of repeating monomers. They can be designed and synthesized to meet certain characteristics to apply in real life. Click chemistry plays an essential role in creating new polymers, including modifying them afterwards. This paper introduces three typical click chemistry reactions in polymer synthesis and modifications, which include Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC), thiol-ene reaction, and Diels-Alder reaction. They all have positive impact in synthesizing and modifying polymer. CuAAC reaction is applied to make desired polymer with crosslinking structure or other desired protein structure and modify the product by introducing new functional groups. Thiol-ene reaction makes good use in producing adhesives, including light-curing adhesive and bio-based adhesive, as well as surface modification. Diels-Alder reaction provides new insights in the synthesized polymers. At last, double click chemistry, which is still at the stage of preliminary exploration, contributes to creating complex polymers. The use of click chemistry in polymers is powerful and useful, leading the development of advanced materials and upgrading synthesizing skills.

Abstract:

Polymers are some of the most widely used materials for human use and have greatly facilitated people's lives. However, with the use of polymer materials, traditional thermoplastic and thermoset materials are unable to meet the more diverse needs, and traditional processing methods are not able to significantly improve the performance of polymer materials. Some researchers have found that by applying the principles of reversible covalent and supramolecular chemistry in dynamic chemistry in the development of polymers, the properties and functions of polymers can be changed from the bottom up. Therefore, this paper analyses the similarities and differences between the principles of reversible covalent chemistry and supramolecular chemistry by collecting applications of reversible covalent chemistry and supramolecular chemistry in the field of polymer synthesis and comparing the two to provide assistance for future developments in the field of polymers.

Abstract:

Micro-polymer chemistry experiment teaching had such characteristics as using less reagents, less pollution and more portable in comparison with the conventional experiment, with the significant progress, more than thirty years ago. In China, Zhou Ninghuai and others firstly began to go on micro-scale experiment research and Professor Li Qingshan who brought this innovation to polymer organic synthesis experiment has done a lot of works in micro-polymer chemistry experiment teaching. To carry out the study of micro-polymer chemistry experiments not only accords with teaching methods and reform, but also conforms to the trend of the times of green chemistry. The research and application of micro-polymer chemistry experiment have broad prospects. The microscale chemistry experiment (ML) is developed from the idea of green chemistry and the prevention of chemical industry. Microscale chemistry presents a low-cost and green approach in the teaching of chemistry laboratory courses, so it’s the reform of traditional chemical methods. In micro-chemistry experiment, most of the raw materials are in the amount of quality 1g or volume of 1mL below, in line with famous micro-chemist Professor Ma Zusheng[1] (Prof • T. S. Ma), who put forward that "It is to use the chemical reagents as low as possible to obtain the necessary technology information in microscale chemical experiments". In contrast to conventional macroscale chemistry experiment, the micro-chemistry experiment can not only reduce the running cost of laboratory teaching, but also alleviate the potential hazard sassociated with chemistry experiments.

Abstract: In this article we are focused on specially application of polymers and what hazards effects will come in future . Because at present time polymer application day by day used in multifunctional work. Here we want to discuss type of polymer. Synthetic polymers having wide applications like as a electronic equipments ,aerospace application, Light equipment , Cardiac heart valves, Polymer base mesh used in prevent of hernia in human body, synthetic polymer rayon useful in textiles industries. Synthetic polymers are vast used in medical sectors ,like as drug delivery, many packing are easily transported from one palace to other palace self-healing, and molecular-recognition materials. Many researchers have synthesized gel materials by designing their molecular and macroscopic structure as well as the constituent materials from the perspective of organic chemistry, physical chemistry, and biochemistry, among others. In addition, the fact that pharmacy, biomedicine, molecular biology, biochemistry, and biophysics are the fields that polymers and polymer chemistry play a significant role in the development of their new areas. It is obvious why the study of giant molecules is one of the most attended and the fastest growing fields of science. Therefore, it seems that polymer is not a specialized interdisciplinary or branch of chemistry. Here I have mention one of the polymers made by me and focused on application of polymers.

Abstract:

Combing active ester chemistry and click chemistry, a cyclic double-grafted polymer was successfully demonstrated via a “grafting onto” method. Using active ester chemistry as post-functionalized modification approach, cyclic backbone (c-P2) was synthesized by reacting propargyl amine with cyclic precursor (poly(pentafluorophenyl 4-vinylbenzoate), c-PPF4VB6.5k). Hydroxyl-containing polymer double-chain (l-PS-PhOH) was prepared by reacting azide-functionalized polystyrene (l-PSN3) with 3,5-bis(propynyloxy)phenyl methanol, and further modified by azide group to generate azide-containing polymer double-chain (l-PS-PhN3). The cyclic backbone (c-P2) was then coupled with azide-containing polymer double-chain (l-PS-PhN3) via CuAAC reaction to construct a novel cyclic double-grafted polymer (c-P2-g-Ph-PS). This research realized diversity and complexity of side chains on cyclic-grafted polymers, and this cyclic double-grafted polymer (c-P2-g-Ph-PS) still exhibited narrow molecular weight distribution (Mw/Mn < 1.10).

Abstract:

Man has been using plastics for thousands of years, and some of the earlier uses of plastics include spoons, buttons and combs. Today, plastics are used for a myriad of applications, such as for aerospace, microelectronics and water purification. With polymer chemistry, man has been able to alter the properties of plastics or polymers to suit almost any application. Their properties can also be tailored for use as advanced biomedical implants in the human body. An example of such a polymer is the biocompatible lactide/glycolide polyesters. These biodegradable polymers are currently used as sutures, drug delivery systems, temporary implants and even as scaffolds for tissue engineering.

Abstract:

Multicomponent reactions (MCRs) have been used to prepare polymers with appealing functions. The Biginelli reaction, one of the oldest and most famous MCRs, has sparked new scientific discoveries in polymer chemistry since 2013. Recent years have seen the Biginelli reaction stepping further from simple coupling tools; for example, the functions of the Biginelli product 3,4-dihydropyrimidin-2(1H)-(thi)ones (DHPM(T)) have been gradually exploited to develop new functional polymers. In this mini-review, we mainly summarize the recent progress of using the Biginelli reaction to identify polymers for biomedical applications. These polymers have been documented as antioxidants, anticancer agents, and bio-imaging probes. Moreover, we also provide a brief introduction to some emerging applications of the Biginelli reaction in materials and polymer science. Finally, we present our perspectives for the further development of the Biginelli reaction in polymer chemistry.

Abstract:

Prior to receiving the Nobel Prize in chemistry in 2000 for my work in polymers, polymer science had been recognized three times. The first Nobel Prize in chemistry for polymer science was awarded in 1953 to Hermann Staudinger, for his pioneering work in the 1920s. At that time, the concept of macromolecules was new, and his ideas were controversial. However, the data prevailed, and he was awarded the Prize “for his discoveries in the field of macromolecular chemistry.” The next major event in polymer science was the discovery and invention of nylon by Wallace Carothers at the Dupont Company in 1935. Although Carothers died as a young man, his discoveries created an industry. I have little doubt that his work was deserving of a Nobel Prize and probably would have been awarded. The next related Prize went to Karl Ziegler and Giulio Natta in 1963 for their work on polymer synthesis in the 1950s. The Ziegler–Natta catalysts made possible the large-scale production of polymers such as polypropylene. They were awarded the Nobel Prize in chemistry “for their discoveries in the field of chemistry and technology of high polymers.” In 1974, the Prize for chemistry went to Paul J. Flory, who was a giant in this field. He was awarded the Nobel “for his fundamental achievements, both theoretical and experimental, in the physical chemistry of macromolecules.”

Abstract:

Silicone polymers were pyrolyzed to form silicon oxycarbides that contained only silicon, oxygen, and carbon. The starting polymers were mainly methyl trichlorosilane with a small amount of dimethyl dichlorosilane. NMR showed that the polymers had a silicon-oxygen backbone with branching and ring units. When the polymer was heated in hydrogen, toluene and isopropyl alcohol, used in production of the polymer, were given off in the temperature range 150 °C to 500 °C. Substantial decomposition of the polymer itself began only above about 700°by evolution of methane. The network of silicon-oxygen bonds and silicon-carbon bonds did not react and was preserved; the silicon-carbon bonds were linked into the silicon-oxygen network. The silicon oxycarbide was stable above 1000 °C, showing no dimensional changes above this temperature. The interior of the silicon oxycarbide was at very low effective oxygen pressure because oxygen diffused slowly in it. There was also a protective layer of silicon dioxide on the surface of the silicon oxycarbide.

Full text

Abstract:

Positron chemistry refers to chemical processes of high-energy positrons injected into molecular substances, the most interesting of which is the formation of positronium (Ps), the hydrogen-like bound state between a positron and an electron. Ps is formed predominantly by fast intra-track radiation chemical processes. In polymers it tends to be localized in intra/inter-molecular open space in the sparsely packed amorphous structure. Whilst short-lived singletpara-positronium (p-Ps) undergoes self-annihilation, the positron in long-lived tripletortho-positronium (o-Ps) annihilates with one of the spin opposite electrons bound in the surrounding polymer molecules. This process is called pick-off annihilation. The pick-off annihilation lifetime reflects the polymer chain packing through the size of the volume, where Ps is localized. Positrons are used to probe the amorphous structure of various polymeric systems. In this article, basic concepts and experimental techniques of positron chemistry in polymers as well as applications to the characterization of functional polymeric materials are overviewed.

Abstract:

Despite several technological processes and products found in everyday life involve polymers, it has been neglected in Chemistry Education. In this paper, the using of spaghetti-like representations in polymer teaching was explored. For this, a short course for undergraduate chemistry students was developed and constituted by two didactic sequences. In each of them one demonstrative experiment (latex lift and photopolymerization) was used to promote practices of externalization of visual models. The analysis of the students' drawings and written texts showed demonstrations of problematized concepts relevant to polymer teaching, whereas the effectiveness of spaghetti-like representations' employment requires further research. The initiative was well-founded and satisfactory within an initial exploratory perspective and implementation of this strategy in regular disciplines can promote the increase of students' interest in polymer chemistry, an essential knowledge area for developing countries that need to build their own technologies and innovation. Keywords: visualization in chemistry, spaghetti representation, teaching of polymer.

Abstract:

Inspired by nature, tunable wettability has attracted a lot of attention in both academia and industry. Various methods of polymer surface tailoring have been studied to control the changes in wetting behavior. Polymers with a precisely controlled wetting behavior in a specific environment are blessed with a wealth of opportunities and potential applications exploitable in biomaterial engineering. Controlled wetting behavior can be obtained by combining surface chemistry and morphology. Plasma assisted polymer surface modification technique has played a significant part to control surface chemistry and morphology, thus improving the surface wetting properties of polymers in many applications. This review focuses on plasma polymerization and investigations regarding surface chemistry, surface wettability and coating kinetics, as well as coating stability. We begin with a brief overview of plasma polymerization; this includes growth mechanisms of plasma polymerization and influence of plasma parameters. Next, surface wettability and theoretical background structures and chemistry of superhydrophobic and superhydrophilic surfaces are discussed. In this review, a summary is made of recent work on tunable wettability by tailoring surface chemistry with physical appearance (i.e. substrate texture). The formation of smart polymer coatings, which adjust their surface wettability according to outside environment, including, pH, light, electric field and temperature, is also discussed. Finally, the applications of tunable wettability and pH responsiveness of polymer coatings in real life are addressed. This review should be of interest to plasma surface science communality particularly focused controlled wettability of smart polymer surfaces.

Full text

Abstract:

Self-assembling cyclic peptide-polymer conjugates were prepared by ‘clicking’ polymers (prepared by RAFT polymerization) to an azide functionalized d-alt-l cyclic octapeptide via the Huisgen 1,3-dipolar cycloaddition reaction. Due to the high graft density, the efficiency of the click chemistry conjugation reaction was found to be highly dependent on the size of the polymer. At relatively low molecular weights, as many as four polymer chains could be grafted to each 8 residue cyclic peptide ring. Evidence for the self assembly of the conjugates into peptide-polymer nanotubes was observed by TEM and IR.

Abstract:

Recent progresses achieved in terms of synthetic procedures allow now the access to polymers of well-defined composition, molecular weight and architecture. Thanks to these recent progresses in polymer engineering, the scope of applications of polymers is far wider than that of any other class of material, ranging from adhesives, coatings, packaging materials, inks, paints, optics, 3D printing, microelectronics or textiles. From a synthetic viewpoint, photoredox catalysis, originally developed for organic chemistry, has recently been applied to the polymer synthesis, constituting a major breakthrough in polymer chemistry. Thanks to the development of photoredox catalysts of polymerization, a drastic reduction of the amount of photoinitiators could be achieved, addressing the toxicity and the extractability issues; high performance initiating abilities are still obtained due to the catalytic approach which regenerates the catalyst. As it is a fast-growing field, this review will be mainly focused on an overview of the recent advances concerning the development of organic and organometallic photoredox catalysts for the photoreticulation of multifunctional monomers for a rapid and efficient access to 3D polymer networks.

Abstract:

Cecil Bawn was a physical chemist with particular expertise in chemical kinetics. Early in his career he made pioneering studies of free radical reactions in the gas phase and, during the war years, on the chemistry of high explosives. From mid career, he was one of the pioneers of polymer chemistry and established and led a strong and diverse group of polymer scientists at the University of Liverpool. He was a private and enigmatic person, with a strong sense of duty. His caring and helpful attitude was greatly appreciated locally by his students and younger faculty members. Nationally, he made outstanding service contributions to physical chemistry and polymer chemistry.

Abstract:

The preparation, utilization, and understanding of high polymers represents one of the great triumphs of chemistry and materials science in the 20th century. Synthetic polymers have traditionally been used as structural materials and electrical insulators. Biopolymers often exhibit interesting electrical response phenomena. A recent article in the MRS BULLETIN, for example, discussed piezoelectric properties of both synthetic and biopolymer systems. The newer, synthetic electroactive polymeric materials, however, represent one of the most exciting current areas of polymer materials science.Many synthetic ionic polymer materials are known; perhaps the first were the polyelectrolytes and crosslinked ion exchange materials. These are materials whose backbone contains charges of one sign, balanced by small counter ions of the opposite sign. Such polyelectrolytes have found very important applications in analytical chemistry, water purification, and chemical processing.Complexes, in which salts are dissolved in neutral polymer hosts, have until recently received less attention. The area of polymer/salt complexes became extremely active following the work of P.V. Wright, who first clearly showed that polyethylene oxide (PEO) is an excellent polymer host for a number of salts, and that the resulting solid polymer/salt complexes are electrical conductors. M. Armand broadened the investigation of electrical properties of polymer/salt complexes and pointed out that these materials might be useful in electrochemical devices, especially batteries.This article will discuss the formation, properties, behavior, and applications of polymer electrolytes and mixed conductors—that is, polymeric materials in which charge is transported either by ions or by ionic and electronic charge motion. Our concentration will be on solvent-free materials—materials in which no small molecule solvents are present. There is substantial interest, and substantial progress, in the area of solvent-swollen polymer electrolytes.

Abstract:

A study is presented on cold plasma treatment of the surfaces of two engineering polymers, polyamide 6 (PA6) and polyoxymethylene (POM-C), by diffuse coplanar surface barrier discharges under atmospheric air conditions. We found that plasma treatment improved the adhesion of both polymers for either polymer/polymer or polymer/steel joints. However, the improved adhesion was selective for the investigated adhesive agents that were dissimilar for the two studied polymers. In addition, improvement was significantly higher for PA6 as compared to POM-C. The observed variation of the adhesion was discussed in terms of the changes in surface chemistry, wettability and topography of the polymer surface.

Abstract:

Recently, multicomponent reactions (MCRs) have attracted much attention in polymer synthesis. As one of the most well-known MCRs, the Kabachnik–Fields (KF) reaction has been widely used in the development of new functional polymers. The KF reaction can efficiently introduce functional groups into polymer structures; thus, polymers prepared via the KF reaction have unique α-aminophosphonates and show important bioactivity, metal chelating abilities, and flame-retardant properties. In this mini-review, we mainly summarize the latest advances in the KF reaction to synthesize functional polymers for the preparation of heavy metal adsorbents, multifunctional hydrogels, flame retardants, and bioimaging probes. We also discuss some emerging applications of functional polymers prepared by means of the KF reaction. Finally, we put forward our perspectives on the further development of the KF reaction in polymer chemistry.

Abstract:

The control of surface chemistry and topography has great technological relevance for numerous applications of polymers in textiles, adhesives, coatings, packaging, membranes, and biomedical implants. Conventionally, chemical modification of polymer surfaces has been achieved through kinetically governed practices that allow little control over the final surface composition or morphology. These chemically generated surfaces are also prone to reconstruction. Hence the development of inexpensive, scaleable routes to impart stable and more complex chemical functionality to polymer surfaces continues to be an active area of research. Apart from surface chemistry, the topography of a polymer surface often plays a determinant role in the adhesive, optical, and wetting characteristics of the surface. Consequently methods to produce surfaces of controlled texture are also of interest. Toward these goals, new, statistical, mechanics-based theoretical approaches, coupled with increased computing power, can now facilitate the first-principles design of polymer surfaces that are chemically and structurally “tailored” for a given application. In this article, we review some of the recent, significant developments in this area.

Abstract:

The 12th International Conference on Polymers and Organic Chemistry (POC'06) was held in Okazaki, Japan, from 2-7 July 2006 and was attended by nearly 200 participants from 20 different countries. This was the second time that POC was held in Japan, the first time was in 1990 (1982, Lyon, France; 1984, Lancaster, UK; 1986, Jerusalem, Israel; 1988, Barcelona, Spain; 1990, Kyoto, Japan; 1994, Venice, Italy; 1996, Wroclaw, Poland; 1998, Maa'ale Hachamisha, Israel; 2000, Tianjin, China; 2002, San Diego, USA; 2004, Prague, Czech Republic).The aim of this series of symposia is to bring together chemists from different chemical fields to define and discuss the most recent developments in the areas of polymer-supported reagents, polymeric catalysts, polymers in medicine and biochemistry, polymers for separations, electro- and light-sensitive functional polymers, polymers for environmental protection, processes within functional polymers, and so on. Plenary lectures were provided by Profs. Yoshio Okamoto (Nagoya University, Japan) and Jean M. J. Fréchet (University of California, Berkeley, USA). Along with the plenary lectures, nine invited lectures featured recent advances in the field of polymer-based chemistry in organic synthesis by David E. Bergbreiter, Kuiling Ding, Shu Kobayashi, Yoon-Sik Lee, Helma Wennemers, Pradeep K. Dhal, Toshihide Inoue, Eiji Yashima, and Peter A. G. Cormack. These lectures, as well as 27 oral presentations of the selected papers, exhibited the strength, diversity, and novelty with which this scientific field is being practiced. In addition, there were 55 poster presentations.Ten articles contributed by the lecturers and the conference chairs of POC'06 appear in this issue of Pure and Applied Chemistry in order to provide a summary of last summer's conference.Shinichi ItsunoPOC'06 Co-chairYasuhiro UozumiPOC'06 Co-chair and Conference Editor

Abstract:

The 1920 paper by Hermann Staudinger, which introduced the groundbreaking theory of the existence of long-chain molecules made up of many covalently linked monomeric units, was remembered in 2020 for the 100th anniversary of its publication. This article and the follow-up works of Staudinger on the subject serve as the basis for the study of macromolecular chemistry and polymer science. Although Staudinger saw the great potential of macromolecules, he most likely did not predict the repercussions of their widespread use. We are confronting an environmental and public health crisis with 6.3 billion metric tons of plastic garbage contaminating our land, water, and air. Synthetic polymer chemists can contribute to a more sustainable future, but are we on the right track? In this regard, this review provides insights into the trends, or perspectives, on the current, past, and future developments in macromolecular chemistry to promote an increased emphasis on “sustainable polymers”.

Abstract:

New methods to synthesize and functionalize polymers are of constant interest to the polymer scientist. The 1,3-dipolar cycloaddition between an azide and terminal alkyne has received much attention since the reports that copper(i) provides high yields and regioselective synthesis of 1,4-substituted 1,2,3-triazoles. This coupling chemistry has been rapidly adopted by polymer scientists in the synthesis and post-polymerization modification of polymers. This Review will provide the historical context of the recent development of the copper-mediated azide–alkyne cycloaddition and its use in polymer science, particularly in dendrimer synthesis/functionalization, surface immobilization/modification, orthogonally functionalizing polymers, and its integration with ATRP (atom transfer radical polymerization).
