Polyvinyl Chloride Addition 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.

Polyvinyl chloride addition of vinyl chloride.

Polyvinyl chloride is a white rigid quite brittle solid. History of polyvinyl chloride. Vinyl chloride h2c chcl or c2h3cl n or c2h3cl cid 6338 structure chemical names physical and chemical properties classification patents literature biological activities safety hazards toxicity information supplier lists and more. 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 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. What is vinyl chloride. Pvc is produced from its monomer vinyl chloride. Pvc comes in two basic forms.

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. Vinyl chloride is used primarily to make polyvinyl chloride pvc. It does not occur naturally and must be produced industrially for its commercial uses. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or 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. 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. About 13 billion kilograms are produced annually.

Pvc is a hard plastic that is made softer and more flexible by the addition of plasticizers the most widely used being phthalates. Vinyl chloride is a colorless gas that burns easily. 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. Pvc is used in the manufacture of numerous products including packaging films and water pipes. This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand. Additives are used to modify the properties of polyvinyl chloride to make it more useful.

Pvc vinyl chloride is an organohalogen compound that has important industrial applications.
