I-Polyvinyl chloride (i-PVC) yi-polymer eyenziwe nge-vinyl chloride monomer (VCM) kwi-peroxide, i-azo compound kunye nabanye abaqalisi okanye ngokwendlela ye-polymerization yamahhala phantsi kwesenzo sokukhanya kunye nobushushu. I-Vinyl chloride homopolymer kunye ne-vinyl chloride copolymer zibizwa ngokudibeneyo njenge-vinyl chloride resin.
I-PVC yayikhe yaba yeyona plastiki inkulu ehlabathini, eyayisetyenziswa ngokubanzi. Isetyenziswa kakhulu kwizinto zokwakha, iimveliso zoshishino, iimfuno zemihla ngemihla, isikhumba somgangatho, iithayile zomgangatho, isikhumba sokwenziwa, imibhobho, iingcingo kunye neentambo, ifilimu yokupakisha, iibhotile, izinto ezikhupha amagwebu, izinto zokutywina, iifayili kunye nokunye.
Ngokwe-scope yesicelo esahlukileyo, i-PVC inokwahlulwa ibe: i-PVC ye-resin yenjongo ngokubanzi, iqondo eliphezulu le-polymerization ye-PVC resin kunye ne-PVC edibeneyo. Injongo ngokubanzi i-PVC resin yenziwe nge-polymerization ye-vinyl chloride monomer phantsi kwesenzo somqalisi; I-polymerization degree ephezulu ye-PVC ibhekisela kwi-resin eyenziwe nge-polymerized ngokudibanisa i-agent ye-chain ukukhula kwi-vinyl chloride monomer polymerization system; I-resin ye-PVC ye-Crosslinked i-resin eyenziwe nge-polymerized ngokudibanisa i-agent e-crosslinking ene-diene kunye ne-polyene kwi-vinyl chloride monomer polymerization system.
Ngokwendlela yokufumana i-vinyl chloride monomer, inokwahlulwa ibe yindlela ye-calcium carbide, indlela ye-ethylene kunye nokungeniswa (EDC, VCM) indlela ye-monomer (ngokwesiko, indlela ye-ethylene kunye nendlela ye-monomer engeniswe ngokudibeneyo ebizwa ngokuba yi-ethylene indlela).
