Polyvinylpyrrolidone, additionally acknowledged as PVP, is a polymer of ethylene pyrrolidone. Due to its unique ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate by way of reacting with polyphenols. By the usage of this method, there are effortlessly residual PVP in the wine.

Thermoplastic resin, hydrolyzed into polyvinyl alcohol in acid or alkaline solvents, is the main raw material for preparing polyvinyl alcohol. When molecules contain photosensitizers, they are sensitive to light and undergo decomposition reactions under the action of ultraviolet light or electron beams, exhibiting positive photosensitive resin properties. It can copolymerize with various monomers with double bonds, introducing various functional groups and possessing different properties.
