1-Ethenyl-2-pyrrolidinone homopolymer PVP

Povidone
Povidone is a synthetic polymer consisting essentially of linear 1-vinyl-2-pyrrolidinone groups, the degree of polymerization of which results in polymers of various molecular weights. Povidone can be applied in different types of pharmaceutical formulations. One application of povidone in solid-dosage form is as a pore-former. Povidone can improve the water solubility of the coating, creating a certain amount of diffusion through an insoluble coating of a tablet.
