Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers contain a carboxyl function group ,so it provides excellent adhesion on metal,especially on aluminum foil. resin film also has a good adhesion on PVC, paper, textile. Because this copolymer also contain vinyl acetate function group, so it also has excellent acid,alkali and sale water resistance.menawhile it has oil and ester solution resistance. This copolymer offers a desirable balance of chemical resistance, solubility, diaphaneity, film strength, and thermoplasticity and it can be mixed and mutual soluble with other resin like alkyd resin, Epoxy resin
