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 polyvinyl chloride structure.
About 13 billion kilograms are produced annually.
However vinyl chloride is mostly unstable thus difficult to store and shows acute toxicity.
Rigid sometimes abbreviated as rpvc and flexible.
This polymerisation reaction proceeds by a free radical mechanism.
This compound is important as the monomer for the production of polyvinyl chloride polymer.
It is a thermoplastic having good resistance to alkalis salts and highly polar solvents and it is flame retardant due to the presence of chlorine in the structure.
This solid form can then be modified with the addition of fillers and plasticisers depending on the task at hand.
Pvc comes in two basic forms.
Polyvinyl chloride is one of the cheapest and most widely used plastics globally.
Pvc vinyl chloride is an organohalogen compound that has important industrial applications.
The polymer product of vinyl chloride polyvinyl chloride is stable storable and non toxic.
The presence of chlorine makes it flame retardant.

Polyvinyl chloride pvc has become a universal polymer with many applications e g for pipes floor coverings cable insulation roofing sheets packaging foils bottles and medical products because of its low cost and physical chemical and weathering properties.
Pvc degrades at relatively low temperatures 100 c in the presence of.
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.
When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc.
Additives are used to modify the properties of polyvinyl chloride to make it more useful.
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.
Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer.
