Polymers vinyl chloride.

Polyvinyl chloride also known as poly vinyl or vinyl commonly abbreviated pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene semi rigid glossy sinks in water. Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride. 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. It also has excellent stretch properties at high temperature making it ideal as a material for secondary processing such as vacuum molding.

Pvc vinyl chloride is an organohalogen compound that has important industrial applications. 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 ch2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst. Cn code description 3903 3905.

Pvc is used in the manufacture of numerous products including packaging films and water pipes. 3904 10 00 00 poly vinyl chloride not mixed with any other substances. Polymers of vinyl chloride and chlorinated polymers of vinyl chloride blended with chlorinated polyolefins download pdf info publication number us3006889a. About 13 billion kilograms are produced annually.

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 treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Major industrial polymers major industrial polymers polyvinyl chloride pvc. Polymers of vinyl chloride or of other halogenated olefins in primary forms.

Pvc comes in two basic forms.
