Poly vinyl chloride monomer.

Explore information about air pollutants contaminants and studies being done. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Vinyl chloride is used primarily to make polyvinyl chloride pvc. Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition.

Rigid sometimes abbreviated as rpvc and flexible. Oxyvinyls offers a full product line of pvc resins suitable for most vinyl. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Polyvinyl chloride is a white rigid quite brittle solid.

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. Pvc comes in two basic forms. About 13 billion kilograms are produced annually. This polymerisation reaction proceeds by a free radical mechanism.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Since vinyl chloride is a monosubstituted ethylene and not a symmetric molecule in principle it could have explicit tacticity as does for example polypropylene. Polyvinyl chloride pvc is a chlorinated hydrocarbon polymer produced commercially from vinyl chloride monomer ch 2 chcl by free radical polymerization in an aqueous suspension process. Polyvinyl chloride pvc or vinyl is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles pipes drinking and wastewater wire and cable insulation medical devices etc.

Vinyl chloride is an organohalogen compound that has important industrial applications. Additives are used to modify the properties of polyvinyl chloride to make it more useful. 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. In practice however vinyl chloride polymerized commercially does not have regular tacticity because the growing end of the chain is a free radical at an sp 2 hybridized carbon.
