Vinyl Chloride Polyvinyl Chloride Structure

Polyvinyl chloride structure 2 pvc is a white brittle solid available in powder form or granules formed through an addition polymerisation reaction between vinyl chloride monomers figure 1.

Vinyl chloride polyvinyl chloride structure. About 80 of production involves suspension polymerization. Second only to pe in production and consumption pvc is manufactured by bulk solution suspension and emulsion polymerization of vinyl chloride monomer using free radical initiators vinyl chloride ch 2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst it is a carcinogenic gas that must be handled with. Oldring in encyclopedia of physical science and technology third edition 2003. Effect of hydrogenation and chlorination reactions on the β relaxation of poly vinyl chloride journal of macromolecular science part b.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Pvc comes in two basic forms. Vinyl chloride is an organohalogen compound that has important industrial applications.

Polyvinyl chloride was synthesized by baumann in the 1870s. Polyvinyl chloride is produced by polymerization of the vinyl chloride monomer vcm. It is insoluble in alcohol and slightly soluble in tetrehydrofuran. Polyvinyl chloride is a white brittle solid.

About 13 billion kilograms are produced annually. 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. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand.

Rigid sometimes abbreviated as rpvc and flexible. This polymerisation reaction proceeds by a free radical mechanism. Pvc is used in the manufacture of numerous products including packaging films and water pipes. Xiv a vinyl chloride containing polymers.

Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics.
