Polyvinyl chloride (PVC) wani polymer ne da aka yi wa polymer da aka yi wa polymer da vinyl chloride monomer (VCM) a cikin peroxide, azo compound da sauran masu farawa ko kuma bisa ga tsarin free radical polymerization a ƙarƙashin aikin haske da zafi. Ana kiran Vinyl chloride homopolymer da vinyl chloride copolymer gaba ɗaya da vinyl chloride resin vinyl chloride.
PVC ta kasance mafi girman robobi a duniya, wanda aka fi amfani da shi sosai. Ana amfani da shi sosai a kayan gini, kayayyakin masana'antu, kayan yau da kullun, fatar bene, tayal ɗin bene, fata ta wucin gadi, bututu, wayoyi da kebul, fim ɗin marufi, kwalaben, kayan kumfa, kayan rufewa, zare da sauransu.
Dangane da nau'ikan aikace-aikacen daban-daban, ana iya raba PVC zuwa: resin PVC na gabaɗaya, babban matakin polymerization na PVC da resin PVC mai haɗin giciye. Ana samar da resin PVC na gabaɗaya ta hanyar polymerization na vinyl chloride monomer a ƙarƙashin aikin mai farawa; Babban matakin polymerization na PVC yana nufin resin polymerized ta hanyar ƙara wakilin haɓaka sarka a cikin tsarin polymerization na vinyl chloride monomer; Resin PVC mai haɗin giciye wani resin polymerized ne ta hanyar ƙara wakilin haɗin giciye wanda ke ɗauke da diene da polyene cikin tsarin polymerization na vinyl chloride monomer.
Dangane da hanyar samun monomer ɗin vinyl chloride, ana iya raba shi zuwa hanyar calcium carbide, hanyar ethylene da hanyar monomer da aka shigo da ita (EDC, VCM) (a al'adance, hanyar ethylene da hanyar monomer da aka shigo da ita gaba ɗaya ana kiranta hanyar ethylene).
