Vinyl Chloride Radical Polymerization

Radical chain growth polymerization of vinyl chloride the following animation illustrates the polymerization of vinyl chloride initiated by radicals.

Vinyl chloride radical polymerization.

To repeat the animation click on the drawing. Relevant mechanisms involved in the heterogeneous free radical polymerization of vinyl chloride have been identified including elemen tary chemical reactions. Polymerization of vinyl chloride vc was studied. Approximately 80 of the world s pvc is produced by the suspension polymerization process.

Vc vc α d 1 vc β β d 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. Natural evolution of hcl from vc occurred in the polymerization. But still the term controlled polymerization is not yet clearly defined. Chemical and physical methods were used to observe irregular structures such as branching double bonds and head to head or tail to tail addition and also to confirm the relation.

The in species represents the initiating radical which might originate from a peroxide or azo initiator. This paper describes the room temperature living radical polymerization lrp of vinyl chloride in h 2 o thf in the presence of cu 0 or cu i salts as catalysts tren or pei as ligands and iodoform as initiator. Suspension bulk emulsion and solution are commercially employed in pvc manufacturing.
