N-Vinylcaprolactam CAS 2235-00-9
N-Vinylcaprolactam (NVC), also known as N-Vinyl-e-caprolactam or n-vinyl caprolactam, is a highly reactive vinyl lactam monomer with the CAS number 2235-00-9. It is a colorless to pale yellow liquid that readily undergoes free-radical polymerization to form water-soluble or thermosensitive polymers.
Due to its balanced hydrophilic and hydrophobic structure, N-Vinylcaprolactam is an important intermediate in the production of copolymers and homopolymers used across a wide range of industries including coatings, adhesives, personal care, and pharmaceuticals.
