Polymerization Of Vinyl Chloride
When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.
Polymerization of vinyl chloride. The participation of chain transfer reactions in the polymerization of vinyl chloride in solutions has been elucidated. Suspension polymerization affords particles with average diameters of 100 180 μm whereas emulsion. Polyvinyl chloride is produced by polymerization of the vinyl chloride monomer vcm as shown. Pvc ranks as the second most important polymer after ethylene.
Chemical and physical methods were used to observe irregular structures such as branching. 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. 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 used in the manufacture of numerous products including packaging films and water pipes.
Isopropyl chloride 2 4 dichloropentane and 2 4 6 trichloroheptane were used as solvents. Natural evolution of hcl from vc occurred in the polymerization. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. Being a very well known memb r of the family of vinyl polymers.
Physical phenomena of polyvinylchloride parti cle formation and reactant species distributions in phas s during poly merization. Polymerization of vinyl chloride have been identified including elemen tary chemical reactions. Emulsion polymerization accounts for about 12 and bulk polymerization accounts for 8.
