Poly Vinyl Chloride Monomer

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer.

Poly vinyl chloride monomer.

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. Polyvinyl chloride is a white rigid quite brittle solid. Pvc comes in two basic forms. Oxychem s affiliate oxyvinyls is the third largest polyvinyl chloride pvc supplier in the united states.

Vinyl chloride is an organohalogen compound that has important industrial applications. About 13 billion kilograms are produced annually. Since vinyl chloride is a monosubstituted ethylene and not a symmetric molecule in principle it could have explicit tacticity as does for example polypropylene. 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.

When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Pvc is used in the manufacture of numerous products including packaging films and water pipes. Vinyl chloride is also produced as a combustion product in tobacco smoke. 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.

Rigid sometimes abbreviated as rpvc and flexible. 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. Oxyvinyls offers a full product line of pvc resins suitable for most vinyl. Explore information about air pollutants contaminants and studies being done.

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. This polymerisation reaction proceeds by a free radical mechanism. Additives are used to modify the properties of polyvinyl chloride to make it more useful. Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials.
