Example Of A Polymer Of Vinyl Chloride
Pvc vinyl chloride is an organohalogen compound that has important industrial applications.
Example of a polymer of vinyl chloride. In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom. For example polyvinyl chloride is an industrial homopolymer synthesized from repeating units of vinyl chloride. A homopolymer is a polymer where every monomer unit mer of the chain is the same. 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.
The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. Vinyl chloride ch2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst. 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. An industrially important example is vinyl chloride precursor to pvc a plastic.
Homopolymer examples polyvinylchloride pvc is a homopolymer consisting of vinyl chloride units. 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 polymers are the most common type of plastic. About 13 billion kilograms are produced annually.
Pvc is used in the manufacture of numerous products including packaging films and water pipes. Pvc comes in two basic forms. In popular usage vinyl refers only to polyvinyl chloride pvc. 5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents to be apply properly.

Chemical structure of polyvinyl chloride pvc industrial polymers are synthesized from simple compounds joined together to form long chains. Their backbone is an extended alkane chain ch 2 chr ch 2 chr. Rigid sometimes abbreviated as rpvc and flexible.
