Polyvinyl Chloride Addition Of Vinyl Chloride

This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand.

Polyvinyl chloride addition of vinyl chloride.

Vinyl chloride is a colorless gas that burns easily. It does not occur naturally and must be produced industrially for its commercial uses. Pvc is produced from its monomer vinyl chloride. Pvc geomembranes are made from pvc resin plasticizer s fillers and additives.

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 vinyl chloride is an organohalogen compound that has important industrial applications. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Pvc comes in two basic forms.

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. The earliest record of polyvinyl carbonate creation dates back to 1872 when a german scientist by the name of eugene baumann found a white solid appearing inside a flask of vinyl chloride. Polyvinyl chloride pvc is one of the most widely produced thermoplastic polymers in the world after polyethylene and polypropylene without the additions of plasticizers pvc is a naturally white brittle plastic. History of polyvinyl chloride.

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. Rigid sometimes abbreviated as rpvc and flexible. 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.

Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. When used as a geomembrane plasticizer additions of 25 35 are common. This polymerisation reaction proceeds by a free radical mechanism. Polyvinyl chloride is a white rigid quite brittle solid.

The vinyl chloride had been exposed to sunlight and the white solid was a rigid polymer pvc. Its most common use is in the construction industry but it is also used to manufacture signs in healthcare applications and as a fiber for clothing. Vinyl chloride is used primarily to make polyvinyl chloride pvc. Pvc is used in the manufacture of numerous products including packaging films and water pipes.

About 13 billion kilograms are produced annually.
