Poly ethylene co vinyl acetate solubility.

Poly ethylene co vinyl acetate vinyl acetate 40 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. This polymer is readily available with a variety of va contents generally ranging from 0 to 40. Linear formula ch 2 ch 2 m ch 2 ch ococh 3 n.

Not only the solubility parameter and the vinyl acetate content but also the molecular weight and polydispersity have an important influence on both phase behavior and pour point depression.

Ethylene vinyl acetate is a copolymer containing the semi crystalline polyethylene and amorphous vinyl acetate and these are commonly used as rate controlling membranes in drug delivery devices.
