Polymerization of vinyl chloride equation. Additives are used to modify the properties of polyvinyl chloride to make it more useful. Chemical and physical methods were used to observe irregular structures such as branching. This polymerisation reaction proceeds by a free radical mechanism. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.

The equation representing the synthesis of polyvinylchloride from vinyl chloride is as follows. Polyvinyl chloride is a white rigid quite brittle solid. Refer to table 11 2. Polymerization of vinyl chloride vc was studied.

Pvc vinyl chloride is an organohalogen compound that has important industrial applications. 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. 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. Specifically workers in polymerization section of a b f.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. The case of vinyl chloride suspension polymerization. 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. Polyvinylchloride is the polymer formed from the polymerization of the monomer vinyl chloride.

Being a very well known memb r of the family of vinyl polymers. Polyvinyl chloride pvc chemical formula. Natural evolution of hcl from vc occurred in the polymerization. Goodrich plant near louisville kentucky were diagnosed with liver angiosarcoma also known as hemangiosarcoma a.

Macromolecular reaction engineering 2009 3 1 16 35. Poly vinyl chloride is also known as poly vinyl or vinyl as abbreviated known as pvc. 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. About 13 billion kilograms are produced annually.

Pvc is used in the manufacture of numerous products including packaging films and water pipes. Importance of radical transfer in precipitation polymerization. Polyvinyl chloride is a white brittle solid.
