What is Polyvinylpyrrolidone PVP ? Polyvinyl pyrrolidone (PVP), a non-ionic polymer, is one of the most distinctive, well-studied and widely studied fine chemicals in N-vinylamide polymers. Has developed into non-ionic, cationic, anionic 3 categories, industrial grade, medical grade, food grade 3 specifications, relative molecular weight from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.
