Polyvinylpyrrolidone CAS 9003-39-8
Polyvinylpyrrolidone (PVP) yog ib tug polymer ntawm vinylpyrrolidone, uas yuav muab faib ua soluble PVP thiab insoluble PVPP vim nws txawv degree ntawm polymerization. Tus txheeb ze molecular hnyav ntawm soluble PVP yog 8000 ~ 10000, uas yuav siv tau raws li ib tug precipitator.
