Descrição geral

Polyvinyl pyrrolidone [poly(N-vinyl-2-pyrrolidone), PVP] is a stable, bulky, non-toxic, non-ionic polymer widely used in medical, industrial, pharmaceutical, food, cosmetic, and electronic applications. It can be prepared from N-vinyl-2-pyrrolidone by free radical polymerization.

Aplicação

PVP can be used as:
  • A stabilizer in the synthesis of metallic nanoparticles (NPs) as it avoids the aggregation of NPs via repulsive forces produced by its hydrophobic carbon chains.
  • A capping agent in the synthesis of rodlike hydroxyapatite (HAp) nanoparticles to control the nucleation and growth of HAp crystal.
  • A synthetic polymer vehicle in the pharmaceutical industry for dispersing and suspending drugs.
  • An emulsifier and disintegrant for solution polymerization.
