ʻO ka polyvinyl chloride (PVC), ka mea i kapa ʻia ʻo PVC, he polymer versatile i hoʻohana ʻia i nā ʻano ʻoihana like ʻole. Hana ʻia ia e ka polymerizing vinyl chloride monomer (VCM) ma o ka mīkini polymerization free-radical me ke kōkua o nā peroxides, nā hui azo a i ʻole nā mea hoʻomaka, a me ka māmā a me ka wela. Aia ka PVC i nā homopolymers vinyl chloride a me nā copolymers vinyl chloride, i hui pū ʻia me nā resins vinyl chloride. Me kona mau waiwai koʻikoʻi a me ka hoʻololi ʻana, ua lilo ʻo PVC i mea koho no nā noi he nui.
