Vinylpyrrolidone/Vinylacetate Copolymers
PVP/VA copolymers produce transparent, flexible, oxygen permeable films which adhere to glass, plastics and metals.
ability to control their hydrophilicity through monomer composition
Polyvinylpyrrolidone/vinyl acetate (PVP/VA) resins are linear, random copolymers produced by the free-radical polymerization of the monomers in ratios varying from 70/30 to 30/70 vinyl acetate to vinylpyrrolidone.
The PVP/VA copolymers are thermoplastic resins with molecular weights from 20M to 50M. Their glass transition temperatures vary from 55 to 109°C and hydrophilicity increases with vinylpyrrolidone content.
