Etheyl Vinyl Acetate

Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va.

Etheyl vinyl acetate.

As the va content increases crystallinity decreases until at 50 the eva is totally amorphous. It shows good chemical resistance. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters.
