Product introduction
Chinese alias: crosslinked polyvinyl pyrrolidone (PVP-P); PVP-P(Crosslinked polymer)
English alias: PVPP

Physical properties: White or near-white powder, insoluble in water, ethanol, ether and other commonly used organic solvents.
Use: Cross-linked polyvinylpyrrolidone (PVP-P) can form complexes with phenols and alkaloids to remove them from plant samples, thus preventing the modification and interference of proteins in order to determine protein content more accurately. It has also been reported that crosslinked polyethylpyrrolidone (PVP-P) can improve the activity of the enzyme
Cross-linked POvidone (PVPP), also known as insoluble polyvinylpyrrolidone, cross-linked polyvinylpyrrolidone, refers to the polymer water insoluble polymer obtained from n-vinyl2-pyrrolidone by cross-linking reaction. The appearance of crosslinked POvidone is white or white powder, no special odor, insoluble in water and various solvents. Crosslinked POvidone has the characteristics of good fluidity, easy processing and high water absorption, and has broad application prospects in the fields of medicine and food processing. The core material of crosslinked POvidone is povidone (PVP). Povidone, also known as polyvinylpyrrolidone, is an n-vinylamide polymer that can be prepared by solution polymerization and bulk polymerization. China is the world’s largest povidone producer, accounting for 50% of the world’s total capacity. However, at present, China’s POvidone enterprises are concentrated in the production of low-end products, high-end products are dependent on imports, which brings certain challenges to the development of crosslinked POvidone industry.
