Polyvinyl Chloride Addition Of Vinyl Chloride

It does not occur naturally and must be produced industrially for its commercial uses.

Polyvinyl chloride addition of vinyl chloride.

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 in the manufacture of numerous products including packaging films and water pipes. 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. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.

Polyvinyl chloride is a white rigid quite brittle solid. Pvc geomembranes are made from pvc resin plasticizer s fillers and additives. 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. Pvc comes in two basic forms.

The vinyl chloride had been exposed to sunlight and the white solid was a rigid polymer pvc. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Vinyl chloride is used primarily to make polyvinyl chloride 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.

Pvc is produced from its monomer vinyl chloride. Additives are used to modify the properties of polyvinyl chloride to make it more useful. Pvc is a hard plastic that is made softer and more flexible by the addition of plasticizers the most widely used being phthalates. History of polyvinyl chloride.

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. When used as a geomembrane plasticizer additions of 25 35 are common. About 13 billion kilograms are produced annually. 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.

Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. Rigid sometimes abbreviated as rpvc and flexible. Vinyl chloride is a colorless gas that burns easily. What is vinyl chloride.
