Methyl methacrylate vinyl acetate copolymer.

Results of methyl methacrylate mma and vinyl acetate voac polymerization using the al ibu 3 2 2 bipyridine tempo initiating system at room temperature failed to confirm the living radical mechanism reported earlier. A series of batch bulk and solution in toluene copolymerizations of methyl methacrylate and vinyl acetate was performed under various reaction conditions to high monomer conversions. Poly ethylene co vinyl acetate graft poly methyl methacrylate eva graft pmma as a modifier of epoxy resins. Methyl methacrylate is also used for the production of the co polymer methyl methacrylate butadiene styrene mbs used as a modifier for pvc.

Polymer international 2002 51 1340 1347. Vinyl acetate methyl acrylate and methyl methacrylate are important monomeric materials used in the manufacturing of polymers and copolymers. Several species apparently propagate without control in a normal free radical process and only above a critical initiator concentration.

Therefore the copolymer of vinyl acetate and methyl methacrylate can be used in the aforementioned fields which are agreeable for polyvinyl acetate and polymethyl methacrylate. The principal application consuming approximately 75 of the mma is the manufacture of polymethyl methacrylate acrylic plastics. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used.

Besides vinyl acetate methyl methacrylate copolymer and their corresponding homopolymers are commercially important components in many paints adhesives and binders 28.
