Abstract:
Methods for the synthesis of urethane acrylates used as new crosslinking agents for hydrophobic UV-curable powder clear coatings were developed. In the synthesis of urethane acrylates, isophorone diisocyanate, glycerin, xylitol, polyethylene glycol and polysiloxane KF-6000, as well as 2-hydroxyethyl acrylate or 2-hydroxyethyl methacrylate, were used. In order to increase the functionality of urethane acrylates, glycerin and xylitol derived from renewable sources were introduced. The chemical structure of the urethane acrylates was verified by IR spectroscopy. UV-curable powder clear coatings were obtained through a combination of urethane acrylates with unsaturated polyester resins. The thermal behavior and crosslinking density were examined using DMA. The obtained coatings were evaluated by performing the following tests: roughness, gloss, scratch resistance, hardness, adhesion to steel and water contact angle. As part of this research, high hydrophobicity and scratch resistance of UV-curable powder clear coatings were developed, which are a VOC-free and economically attractive alternative method for low thermal resistance surface protection, such as for composites, wood and wood-based materials.

Abstract:
The single hydroxyl-terminated urethane acrylate oligomers were synthesized from 2-mercaptoethanol (2-MEOH), alkyl (methyl, butyl, and 2-ethylhexyl) acrylate, and 2,2-azobisisobutyronitrile (AIBN, initiator), with dibutyltin dilaurate (DBTDL) as a catalyst. 2-MEOH was used as a functional chain transfer agent. Poly(alkyl urethane) acrylate oligomers were obtained by the reaction of single hydroxyl-terminated polyalkyl acrylates and 2-isocyanatoethyl acrylate. They were characterized by NMR, FT-IR spectroscopy, rheometer, and DSC. Because poly(alkyl urethane) acrylate oligomers have lower Tg and viscosity than hydroxyl-terminated polyalkyl acrylate oligomers (HTPAO) non-containing urethane groups, they can be used for ultraviolet (UV) curable coatings, inks, and adhesives.

Abstract:
The reactive zwitterionic intermediates, generated from addition of isoquinoline to alkyl propiolates, react with thiazolidin-2,4-dione to afford 3-[1-(2,4-dioxothiazolidin-3-yl)isoquinolin-2(1 H)-yl]acrylates in good yields. Using (Z)-5-arylidenethiazolidine-2,4-diones as the NH-acidic component leads to 3-{1-[( Z)-5-benzylidene-2,4-dioxothiazolidin-3-yl] isoquinolin-2(1 H)-yl}acrylates in moderate to good yields in the absence of any catalysts under mild reaction conditions. The reaction between quinoline, ethyl propiolate, and thiazolidin-2,4-dione leads to ethyl 3-[2-(2,4-dioxothiazolidin-3-yl) quinolin-1(2 H)-yl]acrylate.

Abstract:
The synthesis, characterization and UV-curing of hyperbranched urethaneacrylates (HB-UA) were investigated in this study. They were evaluated as oli-gomers in model UV curable coatings. HB-UAs were synthesized by reaction of an aliphatic hyperbranched polyester of the second generation (HBRG2) and an isocyanate adduct, obtained by the reaction of isophoronediisocyana-te and different hydroxy alkyl acrylates. Their thermal properties and viscosities depend on the degree of modification of HBRG2 and the type of hydroxy alkyl acrylate used. The introduction of a flexible alkoxylated spacer between the HBP core and acrylate end groups reduces steric hindrance by moving the cross linkable acrylate groups away from the HBP core and increase its reactivity. Due to the presence of abstractable H-atoms in the ?-position to the ether links, HB-UAs based on poly(ethylene oxide) monoacrylate are very reactive and do not show oxygen inhibition. The obtained coatings combine a high cross linking density with flexible segments between the cross links, which results in a good compromise between hardness and flexibility and have the potential to be used in different UV-curing applications.

Abstract:
In this study, three PCL-based polyurethane acrylates were synthesized and further formulated into twelve resins for digital light processing (DLP) 3D printing. Three PCL diols with different molecular weights were synthesized via ring-opening reaction of ε-caprolactone on diethylene glycol, with the catalyst stannous octoate. Isophorone diisocyanate (IPDI) was reacted with 2-hydroxyethyl acrylate (2-HEA) and the PCL diols form PCL-based polyurethane acrylates. Twelve resins composed of different percentages of PCL-based polyurethane acrylates, poly (ethylene glycol) diacrylate (PEGDA), propylene glycol (PPG) and photo-initiator were further printed from a DLP 3D printer. The viscosities of twelve resins decreased by 10 times and became printable after adding 30% of PEGDA. The degree of conversion for the twelve resins can reach more than 80% after the post-curing process. By changing the amount of PEGDA and PPG, the mechanical properties of the twelve resins could be adjusted. PUA530-PEG-PPG (70:30:0), PUA800-PEG-PPG (70:30:0), and PUA1000-PEG-PPG (70:30:0) were successfully printed into customized tissue scaffolds. Twelve PCL-based polyurethane photo-curable resins with tunable mechanical properties, cytotoxicity, and degradability were successfully prepared. With the DLP 3D printing technique, a complex structure could be achieved. These resins have great potential for customized tissue engineering and other biomedical application.

Abstract:
Waterborne polyurethane emulsions were synthesized with isophorone diisocyanate(IPDI), dihydromethyl propionic acid(DMPA) and poly-ε-caprolactone glycol(PCL), and then reacted with hydroxy-ethyl acrylate(HEA) and 3-aminopropyltriethoxylsilane(APTES) to cap the terminal -NCO groups. The polyurethane emulsions were used to copolymerize with acrylates to synthesize the modified waterborne polyurethane-acrylate hybrid emulsions. The structure, thermal stability and crystallinity of modified polyurethane were studied by FTIR, TG, XRD and the mechanical properties of modified polyurethane films was also investigated. The results show that crystallization of the modified waterborne polyurethane decreases and thermal stability is improved. When the mass fraction of acrylate is 20% and APTES content is 15%, tensile strength of the modified polyurethane films can reach 23.9MPa and elongation at break is 247%.

Abstract:
Polycaprolactone (PCL) is drawing increasing attention in the field of medical 3D printing and tissue engineering because of its biodegradability. This study developed polycaprolactone prepolymers that can be cured using visible light. Three PCL acrylates were synthesized: polycaprolactone-530 diacrylate (PCL530DA), glycerol-3 caprolactone triacrylate (Glycerol-3CL-TA), and glycerol-6 caprolactone triacrylate (Glycerol-6CL-TA). PCL530DA has two acrylates, whereas Glycerol-3CL-TA and Glycerol-6CL-TA have three acrylates. The Fourier transform infrared and nuclear magnetic resonance spectra suggested successful synthesis of all PCL acrylates. All are liquid at room temperature and can be photopolymerized into a transparent solid after exposure to 470 nm blue LED light using 1% camphorquinone as photoinitiator and 2% dimethylaminoethyl methacrylate as coinitiator. The degree of conversion for all PCL acrylates can reach more than 80% after 1 min of curing. The compressive modulus of PCL530DA, Glycerol-3CL-TA, and Glycerol-6CL-TA is 65.7±12.7, 80.9±6.1, and 32.1±4.1 MPa, respectively, and their compressive strength is 5.3±0.29, 8.3±0.18, and 3.0±0.53 MPa, respectively. Thus, all PCL acrylates synthesized in this study can be photopolymerized and because of their solid structure and low viscosity, they are applicable to soft tissue engineering and medical 3D printing.

Abstract:
The graphene oxides were synthesized form graphite by ultrasonic dispersion in water, N-methylpyrrolidone (NMP), N,N-dimethyl-formamide (DMF), acetone and dimethylbenzene, and the polyurethane acrylates containing the reactive NCO (PACN) were prepared. Then the polyurethane acrylates modified graphene oxide synthesized by ultrasonic dispersion in N-methylpyrrolidone (NMP), N,N-dimethyl-formamide (DMF), acetone were prepared by NCO of PACN reacting with the hydroxyl groups of the graphene oxides. The polyurethane acrylates modified graphene oxide was characterized by Fourier transform infrared spectrometer (FTIR), scanning electron microscope (SEM) and Raman spectra. The FTIR spectra showed that the NCO of PACN reacted with the hydroxyl groups of graphene oxide synthesized by ultrasonic dispersion. The measurement of SEM and Raman spectra showed that the polyurethane acrylates modification didn't change the structure and surface morphology of graphene oxide.

Abstract:
Coumarin and cinnamate derivatives were positioned as either polymer chain ends or side groups to synthesize photoactive macromolecules and gain the ability to reversibly control molecular weight and crosslink density using UV light. The cinnamates and coumarins were reacted onto the polymers via multiple reaction pathways. Polymers were functionalized with coumarin or cinnamate groups via an esterification reaction between hydroxyl functionalities and an acid chloride derivatized coumarin group. In addition to the esterification reaction, cinnamates were also coupled to polymers via a ring opening reaction between a hydroxyl functionalized cinnamate derivative and a maleic anhydride repeat unit copolymerized into the polymer. Both functional groups undergo a [2p + 2p] photodimerization reaction (coumarin groups in the UVA and cinnamate groups in the UVB), which was utilized to crosslink and chain-extend macromolecules. Coumarin dimers possess the additional ability to photocleave and thus reverse when irradiated at 254 nm. The coumarin reversible photodimerization reaction was utilized to reversibly increase the molecular weight and molecular weight distribution of coumarin-functionalized PEG monols and diols. For example, the number average molecular weight of the coumarin-functionalized PEG diol doubled and the molecular weight distribution increased from 1.08 to 2.75 when exposed to 110 J cm-2 of UVA irradiation. Subsequent photocleavage (UVC irradiation, 2 J cm-2) of the chain-extended PEGs, cleaved coumarin dimers decreasing the molecular weight and molecular weight distribution to their original values. A number of poly(alkyl acrylate) and poly(methyl acrylate) systems were functionalized with coumarin groups to study the effect of the glass transition temperature and alkyl ester side group composition on the photodimerization reaction and subsequent crosslinking. The glass transition temperature (Tg) acted as an on/off switch for the photodimerization reaction. While the absolute difference between Tg and irradiance temperature did not affect the rate or extent of photodimerization reaction, polymers with a Tg greater than the irradiance temperature displayed less reaction than those with a Tg lower than the irradiance temperature. The final extent of conversion was controlled by a complex combination of factors including alkyl ester side chain steric bulkiness. Coumarin-functionalized alkyl acrylates based on ethylhexyl acrylate were tested as detachable PSAs. A 98% decrease in the adhesive peel strength was observed after exposure to UVA irradiation. Cinnamate groups were utilized in the design and synthesis of UV-curable hot melt pressure sensitive adhesives (PSAs). The cinnamate groups were attached to the PSAs to provide a method to increase molecular weight and add a small amount of crosslinking leading to an increase the adhesive strength of the PSAs. Broadband UV irradiation from a laboratory scale industrial lamp increased the peel strength of the adhesives. Postcure of the irradiated cinnamate-functionalized UV-curable hot melt PSAs was reduced compared to photoinitiated free-radical photocurable UV-curable hot melt PSAs.

Full text
Abstract:
Controlled free radical polymerization facilitates the production of polymers with highly defined microstructures like traditional ionic polymerization; but in contrast allows for previously unattainable monomer combinations such as acrylic acid in its non-protected form. Incorporation of acrylic acid into styrene was done by random copolymerization of acrylic acid (directly and in its protected form as tert-butyl acrylate) with styrene. Styrene/tert-butyl acrylate (S/t-BuA) as well as styrene/acrylic acid (S/AA) mixtures were copolymerized to form tapered or gradient copolymers. Using an alkoxyamine unimolecular initiator, 2-[N- tert-butyl-2,2-(dimethylpropyl)aminooxy] propionic acid (BlocBuilder RTM), along with additional free nitroxide (SG1), the effect of acid protection on polymerization kinetics and copolymer composition was determined. Adding 4.5 mol% SG1/BlocBuilderRTM greatly improved the control of S/t-BuA copolymerization with low polydispersities (1.14-1.22) whereas the S/AA required higher levels of SG1 to produce polymers with low polydispersities that were comparatively still broader compared to the S/t-BuA system (polydispersities ∼ 1.3-1.4 at 9 mol% SG1/BlocBuilderRTM). S/AA copolymerization required higher SG1 concentrations to compensate for degradation of SG1 by attack from the acrylic acid monomer.

Abstract:
In this work, using the idea of an electrically conducting "functional unit," monomers and polymers with possible electronic and electro-optic applications were synthesized. The synthesis and polymerizations were, in many cases, novel and non-trivial. Dithiafulvene (1,3-dithiole) and variations of this functional unit were synthesized and incorporated into new condensation polymers. Polyesters, polyamides and polyhydrazones were all successfully synthesized and could be cast into films. These new polymers might be applicable as processable conducting materials if compatible dopants are employed or by themselves in the area of third order non-linear optics. Using a (meth)acrylate backbone, a spacer group of six methylene units, and a phenyl-CO₂-phenyl mesogen, linked by an ester group to a strongly polar optically active center containing a methoxy group, three new novel monomers and polymers were designed to exhibit smectic C* liquid-crystal phases. The polymers exhibited liquid crystalline behavior as was shown in differential scanning calorimetry and optical microscopy. Further studies and investigations in the synthesis of pure (meth)acrylate esters and their homopolymers yielded surprising results with regard to the Schotten-Baumann reaction. Interestingly, the use of meth(acryloyl) chloride in this scheme leads to (meth)acrylic anhydride, which is not easily isolable from distillable products. This anhydride is responsible for gelation in the polymerization of glycolate esters, and cannot be removed by work-up with various nucleophiles without disrupting desired ester functions. An S(N)2 method is recommended in this work.

ENGLISH ABSTRACT: Finding use for byproducts from the chemical industry holds many advantages for a country's economy. Synthesis of new monomers from such byproducts adds value to otherwise otherwise low-value material. The synthesis of a new olefin-modified acrylate monomer, 1-methyl-1-propyl-hexyl acrylate (1-MPHA), derived from 1-pentene, is reported. Homopolymerisation of the monomer 1-MPHA was carried out in both benzene and in toluene. The products of full-conversion of the homopolymer poly-(1-MPHA) were characterised by GPC, NMR, TGA and DMA. Kinetic studies of the homopolymerisation process of 1- MPHAwere also undertaken. The monomer 1-methyl-1-propyl-hexyl acrylate (1-MPHA) was copolymerised with methyl methacrylate (MMA). Samples obtained from full conversion copolymerisations at various 1-MPHAIMMAfeed ratios were characterised by GPC, NMR, TGA and DMA. Reactivity ratios of the two monomers were obtained from in situ 1H NMR kinetic studies. 1-MPHA was also copolymerised with vinyl acetate (VAc). Samples obtained from full conversion copolymerisation with a 1-MPHA content ranging from 2 to 16 wt% were characterised by GPC, NMR, TGA and DMA. The solubility parameter and the hydrophobicity of the VAc/1-MPHA copolymers were also determined. Reactivity ratios of the two monomers were obtained from in situ 1HNMR kinetic studies. Further copolymerisation studies with styrene and glycidyl methacrylate as comonomers were undertaken. The chemical analysis and thermogravimetric analysis of the copolymers are reported. In conclusion, the use of 1-methyl-1-propyl-hexyl acrylate as a comonomer results in a reduction in the glass transition temperature, better thermal stability, increased hydrophobicity with an insignificant loss in stiffness of the copolymers. These properties are due to the long and branched chain structure of the 1-MPHA monomer.

Verdere kopolimerisasiestudies met stireen en glisidielmetakrilaat as komonomere is onderneem. Chemiese- en termogravimetriese analises van die kopolimere is gedoen en gerapporteer. Ter afsluiting, die gebruik van 1-metiel-1-propiel-heksielakrilaat as komonomeer het 'n verlaging in die glasoorgangstemperatuur, verhoogde termiesestabiliteit, verhoogde hidrofobisiteit, en 'n klein verlies in die stewigheid (Eng. stiffness) van die kopolimeer tot gevolg. Hierdie eienskappe is as gevolg van die lang, vertakte kettingstruktuur van die 1-MPHA monomeer.

A demand in sustainable polymers has been increased because of the environment concerns and saving finite petroleum resources. Plant oils are promising renewable resources to produce environmentally friendly polymer applications. Soybean oil-based resins such as epoxidized soybean oil (ESO) and acrylated epoxidized soybean oil (AESO) have been well-known functionalized plant oils, but relatively low performances of their polymers and a competition with food production have been disadvantages. Thus, in this study, we designed new plant oil-based acrylates using non-food resources and achieved excellent properties of the acrylates for coatings and thermoset applications. Firstly, we developed coating materials with high mechanical, thermal and coating performances using acrylated epoxidized camelina oil (AECO) as a main acrylate monomer with various meth(acrylates) as reactive diluents Next, acrylated epoxidized cardanol modified fatty acids from camelina oil (AECFA) was successfully synthesized, and a phenolic structure with long aliphatic side chains with acrylic groups was obtained. The novel structure of AECFA provided rigidity into its polymer maintained with flexibility, and AECFA coating material showed better performances in terms of all properties such as mechanical, thermal, viscoelastic, and coating performances, as compared to commercial AESO resin. Finally, acrylated epoxidized allyl 10-undecenoate (AEAU) was developed from 10-undecenoic acid, castor oil derivative. The single fatty ester structure with di-functional acrylates of AEAU had very lower viscosity and showed better thermoset performances than those of triglyceride-based acrylates such as AESO and AECO. Thus, AEAU had a potential to an alternative to AESO for thermoset applications.

Abstract:
In this dissertation, we investigate the continuous synthesis of functional poly(ε-caprolactone) (PCL) and controlled copolymerization of ε-caprolactone (CL) with n-butyl acrylate (BA). In the first part, Ti[O(CH2)4OCH=CH2]4 was synthesized and used to obtain double-bond functionalized PCL. The kinetics of Ti[O(CH2)4OCH=CH2]4 initiated ring-opening polymerization (ROP) of ε-caprolactone was thoroughly investigated and the gelation process of CL/Ti[O(CH2)4OCH=CH2]4/BA/BPO system was monitored by rheological method. Then the cross-linked PCL/PBA networks were in situ synthesized in poly(methyl methacrylate) (PMMA) matrix via reactive extrusion. In the second part, Ti[OCH2CCl3]4 was synthesized and used as difunctional initiator for ROP of ε-caprolactone and atom transfer radical polymerization (ATRP) of n-butyl acrylate. The kinetics of Ti[OCH2CCl3]4 initiated ROP of ε-caprolactone and ATRP of n-butyl acrylate were evaluated. PCL-block-PBA copolymers were synthesized by sequential combination of ROP of ε-caprolactone and ATRP of n-butyl acrylate. Then PBA synthsized by Ti[OCH2CCl3]4 initiated ATRP was used as a macroinitiator, PCL-block-PBA copolymer was in situ polymerized in PMMA matrix in Haake internal mixer to investigate the possibility of producing well-defined in PCL-block-PBA copolymer in PMMA matrix through reactive extrusion
Dans cette thèse, nous étudions la synthèse de poly(ε-caprolactone) (PCL) fonctionnelle ainsi que la copolymérisation contrôlée de l'ε-caprolactone (CL) avec l'acrylate de butyle (BA) dans une matrice polymère thermoplastique via l'extrusion réactive. Dans la première partie, l'initiateur de formule Ti[O(CH2)4OCH=CH2]4 a été synthétisé dans le but d'élaborer de la PCL fonctionnelle. La cinétique de polymérisation par ouverture de cycle (ROP) initiée par Ti[O(CH2)4OCH=CH2]4 a été étudiée. Par ailleurs, un processus de gélification a été mis en évidence par rhéologie lors de la polymérisation simultanée de l'ε-caprolactone et de l'acrylate de butyle. Dans un second temps, ces réseaux ont été élaborés dans une matrice de poly (methyl methacrylate) (PMMA) par voie fondue. Dans la deuxième partie, un initiateur schématisé par Ti[OCH2CCl3]4 a été synthétisé dans le but de coupler 2 techniques de polymérisations contrôlées, à savoir la polymérisation par ROP de l'ε-caprolactone et la polymérisation radicalaire par transfert d'atomes (ATRP) de l'acrylate de butyle. Les cinétiques de polymérisation ont été évaluées et des copolymères PCL-bloc-PBA ont été élaborés. Parallèlement, un macro initiateur porteur de chaînes de polybutylacrylate a été synthétisé par ATRP à partir de Ti(OCH2CCl3)4. Ce dernier a permis d'élaborer un copolymère avec de l'ε-caprolactone dans une matrice PMMA en mélangeur interne. L'objectif de cette dernière partie étant de synthétiser, in situ et en voie fondue dans une matrice thermoplastique, un matériau de structure contrôlée afin d'améliorer les propriétés de la matrice

Abstract:
The potential use of polymeric, functionalized nanoparticles (NPs) as drug delivery vectors was explored. Covalent conjugation of albumin to the surface of NPs via maleimide chemistry proved problematic. However, microwave assisted synthesis of NPs was not only time efficient, but enabled the exploration of size control by changing the following parameters: temperature, microwave power, reaction time, initiator concentration, and percentage of monomer used. About 1.5 g of fluorescently-labeled, carboxylic acid-functionalized NPs (100 nm diameter) were synthesized for a total cost of less than $1. Future work will address further functionalization of the NPs for the coupling of albumin (or other targeted proteins), and tests for in vivo biodistribution.

Abstract:
In this study, the core-shell composite polymer for decontamination from the surface contamination was synthesized by the method of emulsion polymerization and blends of polymers. The strippable polymer emulsion is composed of the poly(styrene-ethyl acrylate) [poly(St-EA)] composite polymer, poly(vinyl alcohol) (PVA) and polyvinylpyrrolidone (PVP). The morphology of the poly(St-EA) composite emulsion particle was core-shell structure, with polystyrene (PS) as the core and poly(ethyl acrylate) (PEA) as the shell. Core-shell polymers of styrene (St)/ethyl acrylate (EA) pair were prepared by sequential emulsion polymerization in the presence of sodium dodecyl sulfate (SDS) as an emulsifier using ammonium persulfate (APS) as an initiator. Related tests and analysis confirmed the success in synthesis of composite polymer. The products are characterized by FT-IR spectroscopy, TGA that were used, respectively, to show the structure, the thermal stability of the prepared polymer. Two-phase particles with a core-shell structure were obtained in experiments where the estimated glass transition temperature and the morphologies of emulsion particles. Decontamination factors of the strippable polymeric emulsion were evaluated with the polymer blend contents.

Abstract:
One of the main problems of liquid radioactive waste (LRW) management is concerned with treatment of decontamination waters containing organic ligands. The organic ligands like oxalic, citric and ethylenediaminetetraacetic acids form stable complexes with radionuclides which puts restrictions on application of many technologies of LRW management. One of the ways of destruction of metallorganic complexes consists in using the catalytic oxidation. However, the heterophase catalytic oxidation is rather problematic due to formation of metal oxides on the catalyst surface and calmatation of meso- and micropores. A possible solution of the above problem can be found in synthesis of macroporous catalysts for oxidation having a regular macroporous structure. The present paper describes the template synthesis of macroporous metalloxide catalysts performed with using siloxane-acrylate microemulsions as templates. The method for impregnation of precious metals (PM) particles into the template, which enables one to produce PM nanoparticles of a specific size and immobilize them in the porous structure of the synthesized metalloxide catalysts, is presented. A possible mechanism of the synthesis of macroporous catalysts is suggested and the comparison of the electronic and photon-correlation spectroscopy results obtained at different stages of catalysts synthesis was conducted.
