Vinyl Chloride Polymerisation

Pvc ranks as the second most important polymer after ethylene. The term polyvinyl chloride or pvc indicates homopo1ymers of vinyl chloride and incorrectly copolymers containing amow1ts of vinyl idene chloride vinyl acetage ethylene propylene or acrylates. 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.

The effect of stirring rate on particle size in the suspension polymerization of vinyl.

Vinyl chloride polymerisation.

Suspension polymerization of vinyl chloride with mixed peroxides 387. This polymerisation reaction proceeds by a free radical mechanism. Well duh it s similar to polyethylene but on every other carbon in the backbone chain one of the hydrogen atoms is replaced with a chlorine atom. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics.

Polymerization of vinyl chloride vc with tert butyllithum tert buli was investigated from the point of controlled polymerization the polymerization of vc proceeded at 30 c to give high polymers. Suspension polymerization of vinyl chloride with a mixture of a suspending agent and a surfactant 385. The redox initiator systems of this invention are comprised of a a free radical generator such as a peroxide and b a reducing. The m n of the polymers increased as a function of the reaction time and polymer yields although the initiator efficiency was low.

Suspension polymerization of vinyl chloride in a stirred reactor 385. About 13 billion kilograms are produced annually. Pvc comes in two basic forms. Rigid sometimes abbreviated as rpvc and flexible.

And here my friends is that monomer vinyl chloride. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Linear dependence of the m n of the polymer and polymer. 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.

Additives are used to modify the properties of polyvinyl chloride to make it more useful. Micro suspension polymerization is a technique that it is widely used on a commercial basis for the polymerization of vinyl chloride monomer into polyvinyl chloride. Structurally pvc is a vinyl polymer. It s produced by the free radical polymerization of vinyl chloride.

This invention reveals a greatly improved redox initiator system for use in such polymerizations. Pvc is used in the manufacture of numerous products including packaging films and water pipes. Being a very well known memb r of the family of vinyl polymers. 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.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Polyvinyl chloride is a white rigid quite brittle solid. Vinyl chloride is an organohalogen compound that has important industrial applications.
