Poly ethylene co vinyl acetate formula.

In ethylene ethyl acrylate copolymer. Poly ethylene co vinyl acetate vinyl acetate 25 wt. C 4 h 6 o 2 y. If unsaturated esters are copolymerized with ethylene either the alcohol moiety may be in the polymer backbone as it is the case in ethylene vinyl acetate copolymer or of the acid moiety e.

To be stored in cool dry and ventilated location and protected from light. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. 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. Ethylene vinyl acetate copolymers are prepared similarly to ld pe by high pressure polymerization.
