VP/VA Copolymers with different rations of N-Vinylpyrrolidone to Vinyl Acetate,soluble in most organic solvents.Which exists in powder,water solution form.VP/VA compolymer forms hard,water-removable and glossy films,it has excellent compatibility with many plasticizers and modifiers,an the hydroscopicity decreases in proportion to the ration of Vinyl acetate.

VP/VA Copolymers produce transparent, flexible, oxygen permeable films which adhere to glass, plastics and metals. Vinylpyrrolidone/Vinyl acetate (VP/VA) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in diferrent ratios. VP/VA Copolymers are available as white powders or clear solutions in ethanol and water.
