2- ethyl methacrylate salts

The catalyst disproportionation in water can be suppressed by using an appropriate cosolvent that stabilizes Cu vx. Cu (such as pyridine). It has been demonstrated that the use of pyridine as a cosolvent for aqueous ATRP of ionic monomers such as sodium 4-styrenesulfonate and 2-(A,A,A-trialkyl-ammonio)ethyl methacrylate salts completely suppressed the catalyst disproportionation and well-defined polyelectolytes were obtained. [Pg.352]

Accordingly, the synthesis of novel cinnamate polymers with high functionality and performance is very important from the viewpoint of both polymer chemistry and practical use. Recently, we have reported the synthesis of polymers with pendant photosensitive moieties such as cinnamic ester and suitable photosensitizer groups by radical copolymerizations of 2-(cinnamoyloxy) ethyl methacrylate with photosensitizer monomers (9), by copolymerizations of chloromethylated styrene with the photosensitizer monomers followed by the reactions of the copolymers with salts of... [Pg.225]

Graft copolymers of polyamides using pre-irradiation gamma-rays techniques have been reported for styrene (130), in solution, in the presence of water (40), in alcohols or acetone solution (131), vinyl acetate (130), methacrylic acid in water (132) or methanol solution (129), methyl (133) and ethyl (130) acrylates, 2-ethylhexyl acrylate (55,134), methyl methacrylate (130), in methanol solution (129), 2-dimethylamino ethyl methacrylate quaternary salts (135), acrylamide in aqueous medium (128,136), acrylonitrile (130,137), and 4-vinyl pyridine in aqueous solution (128). [Pg.104]

The monomer 2-(N-carbazolyl)ethyl methacrylate (CzEMA) was first prepared by reacting 9H-carbazole-9-ethanol with methacryloyl chloride, using an excess of triethylamine, in dichloromethane at 0°C. The yields of reaction were not very high (typically 60%) due to the presence of the nitrogen atom on the monomer, which can trap a proton during the reaction. This protonated monomer is eliminated while making several aqueous washes to remove the excess of salts in the product. The purity of the final monomer was demonstrated by H-NMR (Fig. 6). [Pg.92]

Block copolymers of 23b and alkyl methacrylates [158] and diblock copolymers of 23b with 2-(diethylamino)ethyl methacrylate (23b-DEAEM), 2-(diisopropylamino)ethyl methacrylate (23b-DIPAEM), or 2-(N-morphoHno) ethyl methacrylate (23b-MEMA) exhibited reversible pH-, salt-, and temperature-induced micellization in aqueous solution under various conditions. The micelle diameters were 10-46 nm [238]. The micelles of these hydropho-bically modified polybetaines consist of coronas from 23b and cores from polyDEAEM, polyDIPAEM, or polyMEMA. In aqueous solution, the 23b-MEMA diblock copolymers form micelles with cores of polyMEMA above an upper critical micelle temperature of about 50 °C, and reversibly betainized-DMAEM core micelles below a lower critical micelle temperature of approximately 20 °C [239]. [Pg.198]

Amino- and amido-functionalized monomers can also be polymerized directly with metal catalysts. Living radical polymerization of 2-(dimethylamino)-ethyl methacrylate (FM-5) was achieved with 1-31 (X = Br)/CuBr/L-29 in dichlorobenzene at 50 °C.314 Its ammonium salt (FM-6) was polymerized from the surface of a cross-linked polystyrene latex with CuBr/ L-l in water at 80 °C to generate hydrophilic shells, although there were no data for polymer molecular weight.248 As described above (section II.C.6), (methacrylamides with at least their amido protons unprotected (FM-7, FM-8, and FM-9) can be polymerized with copper-based systems,117168,217,218 but a further optimization seems to be necessary. [Pg.484]

Poly(2-dimethylamino)ethyl methacrylate (pDMAEMA) is a water-soluble cationic pol3maer that contains tertiary amines and shows the proton sponge effect to some extent due to pKa=7.5. Approximately 50% of the amines are protonated at pH 7.2 impl3rmg that the other 50% participate in buffering. The absence of primary and secondary amines indicates that pDMAEMA binds relatively loosely to pDNA compared to polycations such as PEI-25K and other high MW PEI. It has been shown to condense pDNA into 150-180 nm size particles and mediate transfection in different cell types. However, complexes with pDMAEMA are not very stable in physiological salt and serum and since they do not possess attributes other than DNA condensation and modest endoso-mal buffering, attempts have been made to modify them (71)... [Pg.634]

Yanez et al. employed MD simulations for the development of MIPS capable of acting as traps for bile salts [cholate salts] in the aqueous medium [Yanez et al., 2010]. iV-[3-aminopropyl]-methacrylate hydrochloride [APMA HC1], iV,iV-diethylamino ethyl methacrylate [DEAEM] and ethyleneglycol methacrylate phosphate [EGMP] were found as suitable functional monomers from a virtual library of 18 monomers. [Pg.626]

A similar procedure has been presented by the same group for the synthesis of another block copolymer, namely poly[4-vinylbenzoic acid-block-2-N-(morpholino)ethyl methacrylate] (PVBA-PMEMA). The protection of the VBA monomer with a tert-butyl group is essential for the synthesis of the desired copolymer, otherwise a mixture of PVBA-PMEMA diblock and PVBA homopolymer was obtained. The particular copolymer is expected to have interesting solution properties since the PVBA block is a week polyacid, while PMEMA is a conjugated acid, soluble over a wide pH range at room temperature and in the absence of salt [14]. [Pg.295]

Solvent adhesives and reactive adhesives are made from homo- and copolymers of methacrylates, generally methyl and ethyl methacrylate and, occasionally, butyl methacrylate. Monomeric (meth)acrylates are also used in reactive adhesive systems (polymerization adhesives). Poly(ethyIene glycol) dimethacrylates are the basis of anaerobically curing liquid resins (reactive adhesives). They also are added as adhesion promoters to plastisol adhesives. Acrylate-ethylene copolymers, in some cases with a small content of carboxyl groups, are used instead of ethylene-vinyl acetate copolymers as fusible polymers for special hot-melt adhesives. Salts of polyacrylate and acrylate - acrylic acid copolymers are used as thickeners for aqueous adhesive solutions and emulsion-based adhesives. [Pg.13]
