Vinyl Chloride Polymerization Reaction

Polyvinyl chloride is a white rigid quite brittle solid.

Vinyl chloride polymerization reaction. Polymerization of vinyl chloride have been identified including elemen tary chemical reactions. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. To achieve this the free radical polymerization of vinyl chloride was modeled at the elementary reaction level. Vinyl chloride ch 2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst.

Physical phenomena of polyvinylchloride parti cle formation and reactant species distributions in phas s during poly merization. About 13 billion kilograms are produced annually. It is a clear colorless liquid with a sweet fruity smell. Vinyl acetate is an industrial chemical that is produced in large amounts in the united states.

Foaming above the aqueous polymerization mixture can be efficiently reduced in suspension polymerization of vinyl chloride monomer in an aqueous medium contained in a polymerization reactor equipped with a reflux condenser for removal of the heat of polymerization by admixing the polymerization mixture with additives comprising a from 0 002 to 0 007 part by weight of a partially saponified. Vinyl acetate is used to make other industrial chemicals. All elementary reactions occurring during the vcm free radical polymerization were grouped into five reaction families consisting of forward and backward steps cfr figure 2. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.

Additives are used to modify the properties of polyvinyl chloride to make it more useful. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Goodrich plant near louisville kentucky were diagnosed with liver angiosarcoma also known as hemangiosarcoma a. Vinyl chloride is an organohalogen compound that has important industrial applications.

It is very flammable and may be ignited by heat sparks or flames. Specifically workers in polymerization section of a b f. A comprehensive reactor model for batch and semi batch proc esses has been developed on the basis of these. Suspension and emulsion polymerization of vinyl chloride monomer using free radical initiators.

This polymerisation reaction proceeds by a free radical mechanism. 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. 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.
