N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.

2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
It is polydimethylsiloxane elastomer particles suspended in a biocompatible carrier hydrogel of poly-N-vinyl-pyrrolidone (povidone). Significantly more publications exist which investigate this material compared to the other materials, [ 4 ] and it has been the most widely used bulking material used for FI. [ 10 ]
