Polymerisation Of Vinyl Chloride Equation

This polymerisation reaction proceeds by a free radical mechanism.

Polymerisation of vinyl chloride equation.

When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. 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. 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.

In the early 1970s the carcinogenicity of vinyl chloride usually called vinyl chloride monomer or vcm was linked to cancers in workers in the polyvinyl chloride industry. Specifically workers in polymerization section of a b f. Chemical and physical methods were used to observe irregular structures such as branching. Polymerization of vinyl chloride vc was studied.

Vc vc αd 1 vc β βd 2 and vc d 3 were used to study the reactivities of the hydrogen atoms in the polymerization and the β hydrogen atoms contributed to the chain transfer. Emulsion suspension and bulk polymerization. Polyvinyl chloride is a white brittle solid. Chain reaction polymerization sometimes called addition polymerization requires an initiator to start the growth of the reaction.

Pvc ranks as the second most important polymer after ethylene. Natural evolution of hcl from vc occurred in the polymerization. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Being a very well known memb r of the family of vinyl polymers.

The largest family of polymers 3 vinyl polymers are produced by chain polymerization reactions a good example is the free radical polymerization of styrene which is initiated by a free radical r that reacts with styrene. Mol view music credit. Pvc is used in the manufacture of numerous products including packaging films and water pipes. Poly vinyl chloride is also known as poly vinyl or vinyl as abbreviated known as pvc.

About 13 billion kilograms are produced annually. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. Polyvinyl chloride is a white rigid quite brittle solid. Goodrich plant near louisville kentucky were diagnosed with liver angiosarcoma also known as hemangiosarcoma a.

Pvc is the widely third most large using synthetic polymer in world followed by polyethylene polypropene.
