Polymerization Of Vinyl Chloride To Form Polyvinyl Chloride

This alkene undergoes addition polymerization to form polyvinyl chloride pvc a polymer used in pipes and many other products.

Polymerization of vinyl chloride to form polyvinyl chloride.

Pvc polyvinyl chloride manufacturing process of polyvinyl chloride pvc. Pvc is produced by polymerization of vinyl chloride monomer vcm. Poly vinyl chloride pvc is generally produced by suspension polymerization of the gaseous monomer vinyl chloride. Polyvinyl chloride is produced by polymerizationof the vinyl chloridemonomer vcm as shown.

Polymerization of vinyl chloride vc was studied. Pvc and its copolymers are widely used with production topping 14 billion pounds in the us in 1997. Emulsion polymerizationaccounts for about 12 and bulk polymerizationaccounts for 8. Pvc is used in the manufacture of numerous products including packaging films and water pipes.

I polymerization process 2 4 5 6. Draw a segment of polyvinyl chloride containing three monomer units connected head to tail. Polymerization of vinyl chloride produces poly vinyl chloride of high molar mass at low monomer conversions whereas polymerization of ethylene glycol with terephthalic acid produces poly ethylene terephthalate of high molar mass only at very high conversions of the oh and co 2h groups. 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.

Natural evolution of hcl from vc occurred in the polymerization. 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. Polyvinyl chloride is a white rigid quite brittle solid. About 80 of production involves suspension polymerization.

See entries 6 and 9 in table 1 1 for the chemical structures. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. A copolymer of i an alkyl acrylate or alkyl methacrylate and ii a hydroxyalkyl acrylate or hydroxyalkyl methacrylate is used as a secondary protective colloid in the suspension polymerization. The main polymerization methods include suspension emulsion and bulk mass methods.

Additives are used to modify the properties of polyvinyl chloride to make it more useful. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. A the diffusion mechanism of vinyl chloride monomer vcm particles into polymeric chain of polyvinyl chloride pvc. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer.

About 80 of production involves suspension polymerization.
