Vinyl chloride polymer n 1.

Polymers of vinyl chloride definition.

A white water insoluble thermoplastic resin derived by the polymerization of vinyl chloride. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene. Between 2017 and 2018 the exports of vinyl chloride polymers grew by 9 55 from 18 5b to 20 3b. About 40 million tons of pvc are produced each year.

Between 2017 and 2018 the exports of polymers of vinyl chloride halogenated olefins nes decreased by 10 3 from 598m to 536m. Polyvinyl chloride noun chemistry. 1 in popular usage vinyl refers only to polyvinyl chloride pvc. In 2018 polymers of vinyl chloride halogenated olefins nes were the world s 2706th most traded product with a total trade of 536m.

This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene. Local sarcomas were induced following implantation of films. About 13 billion kilograms are produced annually.

Pvc in full polyvinyl chloride a synthetic resin made from the polymerization of vinyl chloride. Mesh a polyvinyl resin used extensively in the manufacture of plastics including medical devices tubing and other packaging. 5 2 human data vinyl chloride is manufactured on a vast scale and exposure involves workers in the production polymerization and processing industries. Their backbone is an extended alkane chain ch 2 chr ch 2 chr.

Vinyl chloride vinyl acetate copolymers were tested in mice by subcutaneous implantation as films or powder. Polymers of vinyl chloride or of other halogenated olefins in primary forms 3904 10 00 00 poly vinyl chloride not mixed with any other substances 3904 10 00 10 in the form of granules for use in certain types of aircraft 3904 10. Vinyl polymers are a group of polymers derived from vinyl monomers of the type ch 2 chr. Used chiefly for thin coatings insulation and pipings.
