Polyvinyl chloride (PVC) shi ne polymer polymerized ta vinyl chloride monomer (VCM) a cikin peroxide, fili azo da sauran masu farawa ko kuma bisa ga tsarin polymerization na kyauta a ƙarƙashin aikin haske da zafi.Vinyl chloride homopolymer da vinyl chloride copolymer ana kiransu tare da guduro vinyl chloride.
PVC ta kasance mafi girman filastik manufa na gabaɗaya a duniya, wanda aka yi amfani da shi sosai.Ana amfani dashi sosai a cikin kayan gini, samfuran masana'antu, abubuwan yau da kullun, fata na bene, fale-falen fale-falen ƙasa, fata na wucin gadi, bututu, wayoyi da igiyoyi, fim ɗin marufi, kwalabe, kayan kumfa, kayan rufewa, fibers da sauransu.
Dangane da nau'in aikace-aikacen daban-daban, ana iya raba PVC zuwa: guduro PVC na gaba ɗaya, babban matakin polymerization na PVC guduro da guduro PVC mai haɗin giciye.Babban manufar PVC resin yana samuwa ta hanyar polymerization na vinyl chloride monomer a ƙarƙashin aikin mai ƙaddamarwa;High polymerization digiri na PVC guduro yana nufin guduro polymerized ta ƙara sarkar girma wakili a vinyl chloride monomer polymerization tsarin;Gurorin PVC mai haɗin gwal ɗin guduro ne wanda aka haɗa shi ta hanyar ƙara wakili mai haɗawa da ke ɗauke da diene da polyene cikin tsarin vinyl chloride monomer polymerization.
Dangane da hanyar samun vinyl chloride monomer, ana iya raba shi zuwa hanyar calcium carbide, hanyar ethylene da shigo da su (EDC, VCM) hanyar monomer (a al'adance, hanyar ethylene da hanyar monomer da aka shigo da ita gaba ɗaya ana kiranta hanyar ethylene).
