Vinyl Chloride Radical Polymerization

Suspension bulk emulsion and solution are commercially employed in pvc manufacturing.

Vinyl chloride radical polymerization.

Polymerization of vinyl chloride vc was studied. Natural evolution of hcl from vc occurred in the polymerization. To repeat the animation click on the drawing. 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.

But still the term controlled polymerization is not yet clearly defined. Physical phenomena of polyvinylchloride parti cle formation and reactant species distributions inphas sduring poly merization. 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. Approximately 80 of the world s pvc is produced by the suspension polymerization process.

Poly vinyl chloride pvc is by volume the third largest thermoplastic manufactured in the world with annual demands close to 30 mton. Radical chain growth polymerization of vinyl chloride the following animation illustrates the polymerization of vinyl chloride initiated by radicals. Owing to the importance of poly vinyl chloride pvc as the second largest plastic in volume after the polyolefins and above styrene polymers the control of the free radical polymerization of vinyl chloride vc is of high industrial and academic interest.
