Development of PVC industry

Polyvinyl chloride (PVC) is a polymer polymerized by vinyl chloride monomer (VCM) in the presence of initiators such as peroxide and azo compound or under the action of light and heat according to the free radical polymerization mechanism, and is an important category of synthetic resin.

PVC, a widely used material

As early as 1835, polyvinyl chloride was discovered by V. Lenio of the United States. When sunlight was used to irradiate vinyl chloride, it formed a white solid, namely polyvinyl chloride.
