1.What is the Poly(1-vinylpyrrolidone-co-vinyl acetate) ?

Copovidone is a water-soluble polymer used to improve the uptake and drug loading of various pharmaceutical agents, including contraceptive patches. In a formulation, traces of peroxides in copovidone can impact the stability of drug substances that are prone to oxidation. Copovidone is a highly extrudable water-soluble thermoplastic copolymer manufactured by the polymerization of 6 parts of the hydrophilic group N-vinylpyrrolidone and four parts of the lipophilic monomer vinyl acetate.
