Poly(1-vinylpyrrolidone-co-vinyl acetate), VP/VA Copolymer (CAS 25086-89-9)
Poly(1-vinylpyrrolidone-co-vinyl acetate) (VP/VA Copolymer) is a high-performance synthetic copolymer polymerized from 1-vinylpyrrolidone and vinyl acetate monomers. As a versatile green functional polymer material, it balances hydrophilic and hydrophobic properties perfectly. It can form uniform, flexible, transparent and breathable protective films on material surfaces, with strong adhesion and excellent film-forming stability. It also has outstanding thickening, dispersing and moisturizing effects, featuring mild formula compatibility and stable performance in conventional application environments. It is a core functional additive for high-end daily chemical and industrial formula systems.
