N-Vinylpyrrolidone

CAS Number: 88-12-0

N-Vinylpyrrolidone (NVP) is the monomer for polyvinylpyrrolidone (PVP) and a versatile reactive diluent in UV-curable systems. PVP exhibits exceptional water solubility, biocompatibility, film-forming ability, and complexation capacity. NVP copolymers are used in pharmaceuticals, personal care, adhesives, and specialty coatings.
