Major industrial polymers major industrial polymers polyvinyl chloride pvc. Cn code description 3903 3905. Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride. Rigid sometimes abbreviated as rpvc and flexible.

Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. 3904 10 00 00 poly vinyl chloride not mixed with any other substances. 5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents to be apply properly. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.

Vinyl chloride ch2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst. About 13 billion kilograms are produced annually. Polymers of vinyl chloride and chlorinated polymers of vinyl chloride blended with chlorinated polyolefins download pdf info publication number us3006889a. Kanevinyl m series which is a vinyl chloride vinyl acetate copolymers has outstanding fluidity in its molten state and is suited to processing at low temperatures.

Second only to pe in production and consumption pvc is manufactured by bulk solution suspension and emulsion polymerization of vinyl chloride monomer using free radical initiators. Polymers of vinyl chloride or of other halogenated olefins in primary forms. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc.
