聚氯乙烯，英文简称PVC，是氯乙烯单体在过氧化物、偶氮化合物等引发剂或在光、热作用下按自由基聚合反应机理聚合而成的聚合物。氯乙烯均聚物和氯乙烯共聚物统称之为氯乙烯树脂。
Polyvinyl chloride, also known as PVC, is a polymer formed by the polymerization of vinyl chloride monomers with initiators such as peroxides and azo compounds, or under the action of light and heat, according to the mechanism of free radical polymerization. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin.
