Polyvinyl chloride, referred to as PVC in English, is a polymer formed by polymerization of vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. . As early as 1835, polyvinyl chloride was discovered by American V. Legnio. When vinyl chloride (VCM) was irradiated with sunlight, a white solid, namely polyvinyl chloride, was formed. Polyvinyl chloride PVC is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively called vinyl chloride resins.
