Polyvinyl chloride (PVC) bụ polymer polymerized site na vinyl chloride monomer (VCM) na peroxide, azo compound na ndị ọzọ initiators ma ọ bụ dị ka free radical polymerization usoro n'okpuru omume nke ìhè na okpomọkụ. Vinyl chloride homopolymer na vinyl chloride copolymer ka a na-akpọkọta ọnụ dị ka resin vinyl chloride.
PVC bụbu plastik kacha ibu n'ụwa niile, nke a na-ejikarị eme ihe. A na-eji ya eme ihe n'ọtụtụ ebe na ihe owuwu ụlọ, ngwaahịa ụlọ ọrụ, ihe ndị dị mkpa kwa ụbọchị, akpụkpọ anụ ala, taịlị ala, akpụkpọ anụ artificial, ọkpọkọ, wires na eriri, ihe nkiri nkwakọ ngwaahịa, karama, ihe ụfụfụ, ihe mkpuchi, eriri na ihe ndị ọzọ.
Dị ka ngwa ngwa dị iche iche si dị, PVC nwere ike kewaa n'ime: resin PVC zuru oke, ọkwa dị elu nke resin PVC polymerization na resin PVC jikọtara ya. Emebere resin PVC zuru oke site na polymerization nke vinyl chloride monomer n'okpuru ọrụ nke onye mbido; Ngosipụta polymerization dị elu nke PVC resin na-ezo aka na resin polymerized site na ịgbakwunye onye na-eto eto na-eto eto na vinyl chloride monomer polymerization system; resin PVC crosslinked bụ resin polymerized site n'ịgbakwụnye ihe ntanetị nwere diene na polyene n'ime sistemu vinyl chloride monomer polymerization.
Dị ka usoro nke inweta vinyl chloride monomer, ọ nwere ike kewaa n'ime calcium carbide usoro, ethylene usoro na mbubata (EDC, VCM) monomer usoro (omenala, ethylene usoro na mbubata monomer usoro na-akpọkọta ọnụ dị ka ethylene usoro).
