Poly vinyl acetate was discovered in germany in 1912 by fritz klatte. In ethylene ethyl acrylate copolymer. Poly ethylene co vinyl acetate vinyl acetate 25 wt. 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.

Poly vinyl chloride co vinyl acetate co vinyl alcohol 1 product result match criteria. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Melt index 8 g 10 min 190 c 2 16kg sorry we cannot compare more than 4 products at a time. Ethylene vinyl acetate copolymers are prepared similarly to ld pe by high pressure polymerization.
