Kev piav qhia:
Nws yog homopolymer sib txuas ntawm cov vinylpyrrolidone ntshiab. Nws yog hygroscopic thiab dawb-flowing hmoov lossis off-white. Nws muaj me ntsis tsw phem. Nws tsis yaj hauv cov kuab tshuaj xws li dej, ethanol thiab ether. Yog li nws qhov hnyav molecule tsis tuaj yeem ntsuas tau. Txawm li cas los xij, PVP muaj peev xwm tsim cov khoom sib xyaw nrog ntau yam tshuaj (xws li "Hu" chav kawm tshuaj uas tuaj yeem ua rau muaj kev hloov pauv ntawm ntau yam cawv thiab dej haus). Tsis tas li ntawd nws yooj yim tshem tawm tom qab lim vim nws tsis yaj.
