Crosslinked polyvinylpyrrolidone (PVPP) can be regarded as a linear PVP molecular chain that is cross-linked through physical or chemical methods. PVPP obtained by different synthesis methods has varying properties due to different crosslinking methods and degrees. According to the different crosslinking degree, PVPP is characterized by super absorbent resin (low crosslinking degree), absorbent gel (medium crosslinking degree) and insoluble matter (high crosslinking degree). Compared to PVP, PVP is a water-soluble polymer, while PVPP can only swell in water. Product name | Crospovidone | |||
