Polyvinyl chloride (PVC) ke polymer e entsoeng ka vinyl chloride monomer (VCM) ka peroxide, motsoako oa azo le li-initiators tse ling kapa ho latela mochine oa mahala oa polymerization tlas'a ketso ea khanya le mocheso.Vinyl chloride homopolymer le vinyl chloride copolymer ka kakaretso li bitsoa vinyl chloride resin.
PVC e kile ea e-ba polasetiki e kholo ka ho fetisisa lefatšeng ka bophara, e neng e sebelisoa haholo.E sebelisoa haholo ka thepa ea kaho, lihlahisoa tsa indasteri, litlhoko tsa letsatsi le letsatsi, letlalo la fatše, lithaele tsa fatše, letlalo la maiketsetso, liphaephe, lithapo le likhoele, filimi ea ho paka, libotlolo, lisebelisoa tse phophomang, lisebelisoa tsa ho tiisa, likhoele joalo-joalo.
Ho ea ka mefuta e fapaneng ea ts'ebeliso, PVC e ka aroloa ka: resin ea PVC ea sepheo se akaretsang, tekanyo e phahameng ea polymerization ea PVC le resin ea PVC e amanang le sefapano.Sepheo se akaretsang sa PVC resin e thehoa ke polymerization ea vinyl chloride monomer tlas'a ketso ea initiator;High polymerization degree PVC resin e bua ka resin e entsoeng ka polymerized ka ho eketsa moemeli oa kholo ea ketane ho vinyl chloride monomer polymerization system;Crosslinked PVC resin ke resin e entsoeng ka polymerized ka ho kenyelletsa motsoako o kopanyang o nang le diene le polyene ho vinyl chloride monomer polymerization system.
Ho ea ka mokhoa oa ho fumana vinyl chloride monomer, e ka aroloa ka mokhoa oa khalsiamo carbide, mokhoa oa ethylene le o tsoang linaheng tse ling (EDC, VCM) mokhoa oa monomer (ka tloaelo, mokhoa oa ethylene le mokhoa oa monomer o tsoang linaheng tse ling o bitsoa mokhoa oa ethylene).
