Polyvinyl chloride (PVC) waa polymer polymer ah oo lagu sameeyay vinyl chloride monomer (VCM) oo ku jira peroxide, azo compound iyo kuwa kale ama iyadoo la raacayo habka polymerization-ka xorta ah ee xagjirka ah iyadoo la adeegsanayo iftiinka iyo kulaylka. Vinyl chloride homopolymer iyo vinyl chloride copolymer waxaa si wadajir ah loogu yeeraa vinyl chloride resin.
PVC-gu wuxuu mar ahaa balaastikada ugu weyn adduunka ee loogu talagalay guud ahaan, taas oo si weyn loo isticmaali jiray. Waxaa si weyn loogu isticmaalaa agabka dhismaha, wax soo saarka warshadaha, baahiyaha maalinlaha ah, maqaarka dabaqa, foornada dabaqa, maqaar macmal ah, tuubooyin, fiilooyin iyo fiilooyin, filim baakado, dhalooyin, agabka xumbo, agabka shaabadaynta, fiilooyinka iwm.
Sida ku cad baaxadda kala duwan ee codsiga, PVC waxaa loo qaybin karaa: resin PVC-ga guud, heer sare oo polymerization PVC resin iyo resin PVC-ga isku xidha. Resin PVC-ga guud waxaa sameeya polymerization of vinyl chloride monomer iyadoo la adeegsanayo ficilka bilaabaha; Resin PVC-ga heerka polymerization sare waxaa loola jeedaa resin polymerized iyadoo lagu darayo wakiilka koritaanka silsiladda ee nidaamka polymerization monomer vinyl chloride; Resin PVC-ga isku xidha waa resin polymerized iyadoo lagu darayo wakiil isku xidha oo ka kooban diene iyo polyene nidaamka polymerization vinyl chloride monomer.
Sida ku cad habka loo helo monomer-ka vinyl chloride, waxaa loo qaybin karaa habka calcium carbide, habka ethylene iyo habka monomer-ka ee la soo dejiyo (EDC, VCM) (dhaqan ahaan, habka ethylene iyo habka monomer-ka ee la soo dejiyo waxaa si wadajir ah loogu yeeraa habka ethylene).
