Polyvinylpyrrolidone PVPP e hokahaneng le sefapano Cas 25249-54-1
Polyvinylpyrrolidone cross-linked (PVPP) ke polymer e kopantsoeng e sa qhibiliheng metsing, li-acid tse matla, metheo e matla le li-solvents tse akaretsang tsa tlhaho, tse entsoeng ke polymerization ea li-monomers tsa vinyl pyrrolidone tlas'a maemo a itseng. Jwalo ka sehlahiswa sa bohlokwa sa dikhemikhale tse ntle tsa polymer, PVPP e na le thepa e mengata e babatsehang le e ikgethang, mme e sebedisitsoe haholo ditlolong, dijong, merianeng le mafapheng a mang.
