Ethylene Vinyl Acetate Copolymer Solubility

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

Ethylene vinyl acetate copolymer solubility.

Synthesis and thermal characterization. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Our water soluble polymer product lines include. Polyvinyl alcohol pvoh ethylene vinyl acetate emulsions eva carboxymethyl cellulose cmc polyanionic cellulose pac specialty polyvinyl alcohol pvoh.

Vinyl acetate ethylene copolymer vae redispersible powders rdps polyvinyl alcohol pvoh fine powder s grades. Ethylene co vinyl acetate copolymers in subcritical and supercritical ethylene and ethylene vinyl acetate mixtures.

Abstract the hansen solubility parameters hsps of two ethylene vinyl acetate eva copolymers with 18 and 33 wt of vinyl acetate and their corresponding homopolymers polyethylene pe and pol. 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. As the va content increases crystallinity decreases until at 50 the eva is. The va comonomer interferes with chain packing reducing crystallinity and thus lowering t m and improving transparency when compared with ldpe.
