Crosslinked polyethylpyrrolidone (PVPP) is a kind of crosslinked polymer which is polymerized from vinylpyrrolidone monomer under certain conditions and is insoluble in water, strong acid, strong base and common organic solvents. As an important polymer fine chemical product,PVPP has many excellent and unique properties, and has been widely used in cosmetics, food, medicine and other fields. Characteristics Crosslinked polyvinylpyrrolidone (PVPP) can be seen as a linear PVP molecular chain by physical or chemical crosslinking. Some properties of PVPP obtained by different synthesis methods are different due to different crosslinking methods and crosslinking degrees. Depending on the degree of crosslinking, PVPP appears as super absorbent resins (low crosslinking), water absorbent gels (medium crosslinking) and insoluble substances (high crosslinking).
