Polyvinyl chloride (PVC) ke polymer ea vinyl chloride monomer (VCM) e ntlafalitsoeng ke peroxide, metsoako ea azo le li-initiator tse ling kapa ka mokhoa o sa lefelloeng oa phetoho ea polasetiki tlasa khanya ea mocheso le mocheso. Vinyl chloride homo polymer le vinyl chloride co polymer li bitsoa vinyl chloride resin.
PVC e ne e le polasetiki e kholo ka ho fetesisa lefatšeng mme e ne e sebelisoa haholo. E sebelisoa haholo ho thepa ea moaho, lihlahisoa tsa indasteri, litlhoko tsa letsatsi le letsatsi, letlalo la mokatong, litene tsa mokatong, letlalo la maiketsetso, liphaephe, lithapo le likhoele, filimi ea ho paka, libotlolo, lisebelisoa tse phophomang, thepa ea ho tiisa, likhoele joalo-joalo.
PVC ke sebopeho sa amorphous sa phofo e tšoeu, e nang le degree e tlase ea branched. Khalase ea eona ea phetoho ea khalase ke 77 ~ 90 ℃, 'me e qala ho bola ka170 ℃. Ho sa le joalo e na le botsitso bo fokolang ba khanya le mocheso: e tla bola 'me e hlahise hydrogen chloride ka holimo ho 100 ℃ kapa kamora nako e telele ea ho pepeseha ha letsatsi, mme e iketsetse ka mokhoa o iketsang oa ho hlophisa lintho, o bakang ho soeufala le ho theoha hoa thepa ea' mele le ea mochini, ts'ebelisong e sebetsang , stabilizer kapa li-additives tse ling li tlameha ho eketsoa ho ntlafatsa botsitso ba PVC.
