Polymerization Of Vinyl Chloride

Being a very well known memb r of the family of vinyl polymers.

Polymerization of vinyl chloride. Pvc ranks as the second most important polymer after ethylene. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. Emulsion polymerization accounts for about 12 and bulk polymerization accounts for 8. 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.

Pvc is used in the manufacture of numerous products including packaging films and water pipes. Natural evolution of hcl from vc occurred in the polymerization. The participation of chain transfer reactions in the polymerization of vinyl chloride in solutions has been elucidated. Isopropyl chloride 2 4 dichloropentane and 2 4 6 trichloroheptane were used as solvents.

Polymerization of vinyl chloride have been identified including elemen tary chemical reactions. Physical phenomena of polyvinylchloride parti cle formation and reactant species distributions in phas s during poly merization. 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. Suspension polymerization affords particles with average diameters of 100 180 μm whereas emulsion.

About 80 of production involves suspension polymerization. A comprehensive reactor model for batch and semi batch proc esses has been developed on the basis of these. Polyvinyl chloride is produced by polymerization of the vinyl chloride monomer vcm as shown.
