Polyvinyl chloride (PVC), yomwe imadziwika kuti PVC, ndi polima yosunthika yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Amapangidwa ndi polymerizing vinyl chloride monomer (VCM) kudzera mu njira yaufulu-radical polymerization mothandizidwa ndi peroxides, mankhwala a azo kapena zoyambitsa zina, komanso kuwala ndi kutentha. PVC imaphatikizapo vinyl chloride homopolymers ndi vinyl chloride copolymers, zomwe zimatchedwa vinyl chloride resins. Ndi mawonekedwe ake apamwamba komanso kusinthasintha, PVC yakhala chinthu chosankha pazinthu zambiri.
