PVP(Polyvinylpyrrolidone)

Categorys: , , , , , , ,

PVP is synthesized via a free radical polymerization reaction starting from the vinylpyrrolidone (VP) monomer, using a free radical initiator such as Azobisisobutyronitrile (AIBN). The water-soluble polymer polyvinylpyrrolidone (PVP), also known as polyvidone or povidone, is created from the monomer N-vinylpyrrolidone. PVP can be chosen based on the desired application properties and is offered in a variety of molecular weights and associated viscosities. PVP is a linear polymer that consists of 1-vinyl-2-pyrrolidone monomers, and appears like a faintly yellow solid. In the 1950s, it was the first synthetic polymer to be used as a hair fixative in place of the insect-derived Shellac.
