Methyl aerylate

General Procedure A (esterification of amine) 1 A 50 wt% methanol solution of methyl acrylate (17 g, 0.2 mol) was added to the methanolic solution of Jeffamine T-3000 (100 g, 0.033 mol). This reaction was allowed to stir at room temperature under a nitrogen atmosphere for 48 h. The reaction was then heated to 50°C for 1 h. methanol and excess methyl aerylate were removed by rotary evaporator. After the dialysis using membrane filter with a MWCO of 3 D in methanol, the product was obtained as a yellow viscous oil (6 g, 98%). H NMR (CDCl, 5),...

The formation of an azomethyne ylide during the photodecarboxylation of N-phthaloyl a-amino acid 1 makes easier the interpretation of the results obtained in the presence of methyl aerylate. If we examine the structure of the reaction product 2, we would easily reeognize the fragments corresponding to the acrylate (colored red), the A-phthaloyl a-amino acid 1 that has lost the carboxylic acid function (colored blue) and the new bond formed (in black) (Scheme 16.6). The... 

Theses polymers are made from acrylic acid, its homologues and their derivatives. Glass like resins were made from esters of aerylic acid in 1877 by Fitting and Peter by Kahlbaum. In 1928, Rohm and Hass, a German Company started commercial development of methacrylic esters. Limited production started in 1933. The rapidly expanding air-force used this plastic in place of glass in the aeroplanes. Most of the early production of "Plexiglass was used up by air-force planes. In 1936, ICI marketed methyl methacrylate sheets as "Perspex".

The two pottant materials studied in this report are plasticized polyvinyl butyral (plPVB) which is easily available and used in safety glass, and a highly stabilized, peroxide crosslinked ethylene/vinyl acetate (EVA) copolymer containing about 33 weight % vinyl acetate (.7). The outer cover/insulator materials studied include polyvinyl fluoride (PVF) and a butyl aerylate/methyl methacrylate graft copolymer (BAgMMA) both are blown films. 

Recently Saunders (39) conducted a detailed study of emulsion latices made from methyl ethyl ketoxime-blocked lEM (lEM-MEKO). Compositions investigated were styrene/-butyl acrylate/IEM-MEKO, styrene/butyl aerylate/IEM-MEKO latex formulated with active hydrogen compounds and styrene/butyl acrylate/IEM-MEKO copolymerized with vinyl acids or hydroxy monomers. The effect of urethane catalysts on the deblocking/curing reaction was also studied. 

The mechanisms involved in monomer removal by post polymerisation were studied. Three redox initiator systans which generate radicals with different hydrophobidties were investigated tert-butyl hydroperoxide, hydrogen peroxide and potassium persulphate. Ascorbic acid was used as a reductant in all cases. The efficiency of these initiator systems for the removal of residual monomers from commercial latexes was studied. The examples exauuued were removal of unreacted vinyl acetate from a vinyl acetate/butyl aerylate/acrylie acid latex, methyl methacrylate from a methyl aaylate, butyl aaylate/acryhc acid latex and butyl acrylate from a butyl aaylate/styrene/ acrylic acid latex. Efficieucy of monomer ranoval by post polymerisation increased with the hydrophobidty of the radical formed from the initiator system and this was independent of the water solubihty of the residual monomer. Reasons for the observations were discussed. 35 refs.

Acrolein eould be grafted onto imidazole-eontaining polymers [poly4(5)-vinylimidazole) or copolymers of 4(5)-vinylimidazole with aeryl amide, styrene, l-vinyl-2-pyrrolidone, 4-vinylpyridine, aerylates, and methyl vinyl ketone] in ethanol or an ethanol-water mixture at 0°C under nitrogen [115-117].

Alkyl groups ean include methyl, butyl, isobutyl, 2-ethylhexyl, isodecyl and lauryl. As the munber of carbon atoms in the alkyl groups is inereased, the Tg and brittle point for both types of polymers decreases till about Cs, for poly(alkyl aerylates), and C12, for poly(alky methacrylates), then they rise again. The poly(alkyl methacrylate) has a considerably higher Tg and brittle...
