Description PVP has biocompatibility, low toxicity, adhesive characteristics, complexing stability, relatively inert behavior, and is resistant to thermal degradation. It is readily prepared by the polymerization of N-vinyl-2-pyrrolidone or by Reppe synthesis technique.
Application Polyvinylpyrrolidone (PVP),also known as K90 is a water soluble polymer with good bio-stability. It is chemically stable, has low toxicity and is biocompatible. Hence, it is useful in a variety of s such as cosmetics, tissue engineering, and biomedical engineering.
