Description
Polyvinylpyrrolidone (polyvidone, povidone, or PVP) is a synthetic water-soluble polymer consisting of linear 1-vinyl-2-pyrrolidinone groups. It is hygroscopic and readily absorbs up to 40% of water by its weight. It has excellent wetting properties in solution and easily forms films, which makes it suitable for use as a coating additive.PVP can be synthesized from its monomer N-vinylpyrrolidone via free-radical polymerization in the presence of AIBN as an initiator. In chemical industries, PVP is widely used as a surface stabilizer, growth modifier, nanoparticle dispersant, and reducing agent.
