Abstract (sommario):

The synthesis of novel branched/star copolymers which possess unique physical properties is highly desirable. Herein, a novel strategy was demonstrated to synthesize poly(ε-caprolactone) (PCL) based miktoarm star (μ-star) copolymers by combining ring-opening polymerization (ROP), styrenics-assisted atom transfer radical coupling (SA ATRC), and atom transfer radical polymerization (ATRP). From the analyses of gel permeation chromatography (GPC), proton nuclear magnetic resonance (1H NMR), and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), well-defined PCL-μ-PSt (PSt: polystyrene), and PCL-μ-PtBA (PtBA: poly(tert-butyl acrylate) μ-star copolymers were successfully obtained. By using atomic force microscopy (AFM), interestingly, our preliminary examinations of the μ-star copolymers showed a spherical structure with diameters of ca. 250 and 45 nm, respectively. We successfully employed combinations of synthetic techniques including ROP, SA ATRC, and ATRP with high effectiveness to synthesize PCL-based μ-star copolymers.

Abstract (sommario):

Atom transfer radical polymerization (ATRP) is one of the most successful techniques for the preparation of well-defined polymers with controllable molecular weights, narrow molecular weight distributions, specific macromolecular architectures, and precisely designed functionalities. ATRP usually involves transition-metal complex as catalyst. As the most commonly used copper complex catalyst is usually biologically toxic and environmentally unsafe, considerable interest has been focused on iron complex, enzyme, and metal-free catalysts owing to their low toxicity, inexpensive cost, commercial availability and environmental friendliness. This review aims to provide a comprehensive understanding of iron catalyst used in normal, reverse, AGET, ICAR, GAMA, and SARA ATRP, enzyme as well as metal-free catalyst mediated ATRP in the point of view of catalytic activity, initiation efficiency, and polymerization controllability. The principle of ATRP and the development of iron ligand are briefly discussed. The recent development of enzyme-mediated ATRP, the latest research progress on metal-free ATRP, and the application of metal-free ATRP in interdisciplinary areas are highlighted in sections. The prospects and challenges of these three ATRP techniques are also described in the review.

Abstract (sommario):

Atom transfer radical polymerization (ATRP) is one of the most robust tools to prepare well-defined polymers with precise topologies and architectures. Although series of improved ATRP methods have been developed to decrease the metal catalyst loading to parts per million, metal residue is the key limiting factor for variety of applications, especially in microelectronic and biomedical area. The feasible solution to this challenge would be the establishment of metal-free ATRP. Since 2014, organocatalyzed ATRP (O-ATRP) or metal free ATRP has achieved significant progress by developing kinds of organic photoredox catalysts. This review highlights the advances in organocatalyzed atom transfer radical polymerization as well as the potential future directions.

Abstract (sommario):

Catalysts are essential for mediating a controlled polymerization in atom transfer radical polymerization (ATRP). Copper-based catalysts are widely explored in ATRP and are highly efficient, leading to well-controlled polymerization of a variety of functional monomers. In addition to copper, iron-based complexes offer new opportunities in ATRP catalysis to develop environmentally friendly, less toxic, inexpensive, and abundant catalytic systems. Despite the high efficiency of iron catalysts in controlling polymerization of various monomers including methacrylates and styrene, ATRP of acrylate-based monomers by iron catalysts still remains a challenge. In this paper, we review the fundamentals and recent advances of iron-catalyzed ATRP focusing on development of ligands, catalyst design, and techniques used for iron catalysis in ATRP.

Abstract (sommario):

Atom transfer radical polymerization (ATRP) is a kind of controllable reactive radical polymerization method with potential application value. The modification of graphene oxide (GO) by ATRP reaction can eﬀectively control various graft polymer molecules Chain length and graft density, giving GO diﬀerent functionality, such as good solvent dispersibility, environmental sensitive stimulus responsiveness, biocompatibility, and the like. In this paper, ATRP reaction and GO surface non-covalent bonding ATRP polymer molecular chain were directly initiated from GO surface immobilization initiator. The ATRP reaction modified GO was reviewed, and the process conditions and research methods of ATRP modification reaction were summarized, as well as pointed out the functional characteristics and application prospect of GO functionalized composites.

Abstract (sommario):

AbstractDuring the last decade, atom transfer radical polymerization (ATRP) received significant attention due to its exceptional capability of synthesizing polymers with pre-determined molecular weight, well-defined molecular architectures and various functionalities. It is economically and environmentally attractive to adopt ATRP to aqueous dispersed media, although the process is challenging. This review summarizes recent developments of conducting ATRP in aqueous dispersed media. The issues related to retaining “controlled/living” character as well as colloidal stability during the polymerization have to be considered. Better understanding the ATRP mechanism and development of new initiation techniques, such as activators generated by electron transfer (AGET) significantly facilitated ATRP in aqueous systems. This review covers the most important progress of ATRP in dispersed media from 1998 to 2009, including miniemulsion, microemulsion, emulsion, suspension and dispersed polymerization.

Abstract (sommario):

Photoinduced atom transfer radical polymerization (ATRP) was achieved using a simple household fluorescent lamp as the light source. In solution, methyl methacrylate could be polymerized to welldefined polymers; the photoinduced ATRP system did only convert monomers during irradiation and was inactive in the dark. In situ monitoring by UV-vis spectroscopy revealed the photoredox cycle between Cuᶦᶦ and Cuᶦ species. The linear development of the polymer number average molar mass with monomer conversion, the low dispersity as well as chain extension experiments showed the controlled nature of the polymerization. Photoinduced ATRP was also used to prepare homo- and block copolymer brushes and patterned brushes on surfaces by photoinduced surface-initiated ATRP (PSI-ATRP).

Abstract (sommario):

Sherrington and co-workers have shown that branched vinyl polymers can be synthesized by the addition of a chain transfer agent to a conventional free radical statistical copolymerisation of a vinyl and a divinyl monomer. In the presence of the chain transfer agent, the molecular weight of the primary chains is reduced, gelation can be suppressed and soluble, branched polymers are obtained as the sole product. Living polymerisation techniques offer a way to control the primary chain length without the need for a transfer agent simply by adjusting the monomer/initiator molar ratio. It is suggested that a significant degree of intramolecular cyclisation is the most likely explanation for the remarkable delay in the onset of gelation.

Abstract (sommario):

Unilever would like to explore the use of functional polysaccharides in then detergency formulations. The aim of this work was to grow various polymer chains of pre-determined lengths via Atom Transfer Radical Polymerisation (ATRP), from a water-soluble polysaccharide and to understand and improve the process. This work has given Unilever the option to fine tune polysaccharide-graft-copolymers for industrial use, whilst also satisfying a full investigation of these novel initiators, using new techniques developed within this work. In this respect, 'controlled or living' growth of chains from a post-modified, water soluble polysaccharide is reported for the first time using the following water soluble monomers: 4-styrene sulfonic acid sodium salt, 2-(dimethylamino)ethyl niethacrylate, poly(ethylene glycol) methacrylate and sodium methacrylate. Examples of psuedo first order control plots were seen, with linear increase in molecular weight (PDi values from 2 to 1.2) and with high monomer conversions. The addition of a non-ii ATRP appeared to increase monomer conversion.

Abstract (sommario):

La polimerizzazione radicalica a trasferimento di atomo (ATRP) è una tecnica versatile per la sintesi controllata di strutture macromolecolari. In questo lavoro, un sistema ad attivatore rigenerato mediante trasferimento elettronico (ARGET) ATRP viene presentato come un nuovo sistema green per la sintesi del polistirene (PS). Tale processo ARGET ATRP è catalizzato da rame e il sistema riducente è composto da acido ascorbico e carbonato di sodio. La miscela di solventi è composta da acetato di etile ed etanolo. Sorprendentemente, in specifiche condizioni ARGET ATRP, il PS è gelificato. La gelificazione è sorprendente poiché non sono stati aggiunti agenti ramificanti o reticolanti alla miscela di reazione e la loro formazione in situ è stata esclusa. I risultati sperimentali portano all'ipotesi che si formi una rete olimpica con macrocicli compenetranti. Un brevetto è stato anche depositato con la sorprendente scoperta. In questa tesi viene studiato il meccanismo della gelificazione anomala, le evidenze a supporto dell'ipotesi della rete olimpica e la morfologia dei gel polistirenici ottenuti. Inoltre, è stata studiata anche l'addizione radicalica a trasferimento di atomo (ATRA) per sintetizzare acidi γ-alocarbossilici, partedo da da acidi α-alocarbossilici e alcheni. Gli acidi γ-alocarbossilici possono ciclizzare rapidamente per formare γ-lattoni, a seguito di una reazione di sostituzione della funzione alogenata da parte dell'acido carbossilico. Viene quindi proposta un nuovo acronimo per l'accoppiamento dell'ATRA con la successiva lattonizzazione (ATRA-L). Poiché la frazione alogenata viene persa rapidamente, l'ATRA-L consente l'uso di alcheni generalmente proibiti in ATRA. Infatti, a seguito di una reazione ATRA, l'alogeno del prodotto deve essere inattivo nei confronti di una seconda ATRA, altrimenti si otterrebbe un oligomero. In ATRA-L, l'alogeno viene perso e non ci sono restrizioni sulla scelta dell'alchene. È stato condotto uno studio approfondito della letteratura per trovare le reazioni correlate all'ATRA-L e per collegarle da un punto di vista comune. Viene quindi studiato un sistema ATRA-L catalizzato da rame in acqua, concentrandosi sull'effetto del pH sulla reazione, su come le variabili influenzano il sistema e sul meccanismo di reazione.
Atom transfer radical polymerization (ATRP) is a powerful technique for the synthesis of controlled macromolecular structures. In this work, an activator regenerated by electron transfer (ARGET) ATRP system is presented as a new green system for the synthesis of polystyrene (PS). This ARGET ATRP system is copper-catalyzed and the reducing system is composed of ascorbic acid and sodium carbonate. The solvent mixture is made up of ethyl acetate and ethanol. Surprisingly, in specific ARGET ATRP conditions, the PS gelled. The gelation is surprising since no branching nor crosslinking agents were added to the reaction mixture and their formation in situ was excluded. The experimental results lead to the hypothesis that an olympic network with interpenetrating macrocycles is formed. Furthermore, a patent was filed with the surprising discovery. In this thesis, it is studied the mechanism of the anomalous gelation, the supporting evidence to the olympic network hypothesis, and the morphology of the obtained PS gels. Besides, atom transfer radical addition (ATRA) was also studied to synthesize γ-halocarboxylic acids, starting from α-halocarboxylic acids and alkenes. The γ-halocarboxylic acids can rapidly cyclize to form γ-lactones, following a substitution reaction of the halogenated moiety by the carboxylic acid. A new acronym is then proposed for the combination of ATRA with the subsequent lactonization (ATRA-L). Since the halogenated moiety is rapidly lost, the ATRA-L allows the use of alkenes that are generally prohibited in ATRA. In fact, following an ATRA reaction, the halogen of the product is required to be inactive toward a second ATRA, otherwise an oligomer is obtained. In ATRA-L, the halogen is lost and there are no restrictions on the choice of the alkene. An in-depth study of the literature was done to find the reactions related to ATRA-L and to connect them from a common point of view. A copper-catalyzed ATRA-L system in water is then studied, focusing on the effect of the pH on the reaction, on how the variables affect the system, and on the reaction mechanism.

Abstract (sommario):

Preparation of functional bio-responsive polymer-based materials is the subject of increasing research efforts. Such type of materials could find broad applications in biology and medicine due to their promising performance in the areas of drug and biomolecule delivery, tissue engineering and diagnostic systems. The preparation of such materials has significantly advanced over last 20 years due to the development of reversible deactivation radical polymerization (RDRP) methods. Atom transfer radical polymerization (ATRP), the most often used RDRP procedure, is a versatile and powerful technique for preparation of various functional polymers. Even though ATRP showed great potential for design and synthesis of materials for biomedical applications, there are still many improvements and innovations that should be made in order to effectively utilize this method for production of useful biomaterials. This dissertation seeks to obtain the information required for improving the understanding of several aspects of ATRP, primarily focusing on controlling the polymerization in aqueous media, and how this contributes to the preparation of materials relevant to the biomedical field. Accordingly, this dissertation is divided into VIII chapters, where Chapter I is an introduction to the ATRP in aqueous media and reviews state of the art of aqueous ATRP and materials prepared by this method. Protein-polymer hybrids (PPH) are commercially available therapeutics for treatment of various diseases. Over the last decade the traditional procedure employed for preparation of PPHs had been “grafting-to”, i.e. attaching a preformed polymer to a biomolecule. This technique was challenged by a new approach “grafting-from”, where a well-defined polymer can be grown directly from a specific site on a biomolecule. This method significantly improves purification procedures and yield, which can potentially bring the cost down. Grafting-from requires performing the polymerization under aqueous conditions, optimally under biocompatible conditions. However, conducting ATRP in homogeneous aqueous media is inherently difficult due to multiple side reactions and high reaction rates.

Abstract (sommario):

Polymeric microcapsules can be fabricated by using kernel process called “micro chemical plant system”. The size of microcapsules is more uniform than those made in the conventional pathways. Spherical microcapsules are fabricated through the innovative conjunction of the well-defined amphiphilic block copolymer and stable microfluidic procedure. Crossed microchannel chemical plant are fabricated by using double deep reactive ion etch (DRIE) on 400 μm-thick silicon wafer. The width and depth of this are 100 μm, respectively. PS-b-PMMA copolymer is synthesized by atomic transfer radical polymerization (ATRP) and molecular weight and poly dispersity index (PDI) is 9837 g/mol and 1.08, respectively. With the introduction of two immiscible fluids into the microchannel, droplet flows are visualized by using a high speed CCD camera. The microcapsule was formed due to supramolecular self-assembly of copolymer in the droplet. The characteristics of the produced microcapsules were measured by SEM. A new microfilter was also introduced to separate microcapsule from the suspension fluid.

Abstract (sommario):

Magneto-rheologiacal Fluid (MRF), suspensions of polarizable micron size particles, is synthesized from suspensions of iron particles (micron and nano size) in phosphate buffered saline (PBS). The iron particles have been surface coated using atom transfer radical polymerization (ATRP) with various polymers, such as poly(N-isopropylacrylamide) (poly(NIPAAm)), and poly(acrylamide) (poly(AAm)). The surface grafted polymer has been characterized using differential scanning calorimetry (DSC), and properties of resulting fluid have been measured using a rheometer. A mathematical model is developed to explore the force induced by the particles on the neighboring tissue under externally applied magnetic field. This force results in the damage of the tumor cell lines and trigger the immune system response. The effect of MRF on primary and metastasized tumor growth were evaluated by using an orthotopic murine breast cancer model (4T1). Tumors were evaluated by growth measurements and histological changes following injection of MRF or carrier fluid alone into the tumor and the effects of subsequent application of a magnetic field to the site. Results indicate slowed tumor growth and increased dendritic cell activation with this therapy and they are encouraging.

Abstract (sommario):

Monitoring of systemic effects during rt-PA therapy has shown of depletion of fibrinogen-antiplasmin, plasminogen and other hemostatic factors. Because in vitro activation of plasminogen may occur between blood collection and freezing and thawing before assaying we analysed the influence of 0,0.2, 2.0 and 10.0,ug rt-PA/ml citrate blood (final conc.) on hemostatic and fibrinolytic parameters and its inhibition by 3 different inhibitors. Addition of rt-PA to citrated whole blood without an inhibitor induced a concentration-dependent depletion of Fbg, Plgα2-Apl,α2-M, C1 - I, α2-Atrp, a loss of activity of FV, VIII,IX, XIII and alterations of the global coagulation assays. No effect of rt-PA was observed on F II, VII, X, XI, XII, AT III and Protein C. To prevent in vitro fibrinogenolysis 0.1, 0.5 and 1 mg/ml of a polyclonal sheep anti-rt-PA-antibody, 0.3, 1.0 and 10 Aimol/1 PPACK (D-Phe-Pro-Arg-CH2Cl), 75 and 150 KlU/ml aprotinin (final conc.) and saline as a control were added to pooled citrate blood.All samples containing rt-PA and/or inhibitors and/or saline were incubated for 45 min on ice, centrifuged, aliquotted, snap frozen and stored at ™20° C until analysis. Pretreatment of blood samples with anti-rt-PA IgG prevented interferences with all fibrinolytic and most clotting assays in plasma at a dose of 2 ,ug rt-PA/ ml. PPACK was of limited utility in clotting assays, but enabled correct analysis of fibrinolytic assays. Aprotinin was suitable only for a restricted range of both assay types. It is concluded that collection of blood samples on an appropriate antibody may be the most suitable procedure to get correct measurements of in-vivo effects of rt-PA on the hemostatic system in patients undergoing fibrinolytic therapy.

Abstract (sommario):

The California Freight Mobility Plan 2020 lists the Los Angeles-Inland Empire trade corridor region as a prominent industrial hub experiencing an increase in freight flows. The California Freight Mobility Plan also regards automated truck platoon (ATP) as an emerging opportunity to minimize congestion on the trade corridor routes. Percentage change in accessibility from 2022 (“without” ATP) to 2040 (“with” ATP) is calculated for the eighteen industry sectors of the Los Angeles-Inland Empire trade corridor. The application of the accessibility formulation was carried out with data on travel time from I-710 and I-10 within Los Angeles County. The findings suggest that all the industry sectors have a very high positive percentage change in accessibility by transforming from “without” to “with” ATP deployment-based accessibility. In the vicinity of the prominent freight corridors of I-710 and I-10 within Los Angeles County, notably, the largest increase in accessibility above 90% will be observed for the industry sectors of Agriculture, Forestry, Fishing and Hunting, Health Care and Social Assistance, Finance and Insurance, Transportation and Warehousing, and Retail Trade of the Los-Angeles-Inland Empire. Thus, these findings suggest the deployment of ATP on specific freight routes to enhance and sustain economic activity across the Los Angeles-Inland Empire trade corridors.
