Polymer Of Vinyl Chloride Example

Polyvinyl chloride pvc or vinyl is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles pipes drinking and wastewater wire and cable insulation medical devices etc.

Polymer of vinyl chloride example. Vcm and water are introduced into the reactor and a polymerization initiator along with other additives. Rigid sometimes abbreviated as rpvc and flexible. 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. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.

Under the action of the initiators the. Vinyl polymers are the most common type of plastic. 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. 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.

About 13 billion kilograms are produced annually. Vinyl chloride ch 2 chcl also known as chloroethylene is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst it is a toxic and carcinogenic gas that is handled under special protective procedures. Pvc comes in two basic forms. Vinyl polymers are a group of polymers derived from vinyl monomers of the type ch 2 chr.

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. Poly vinyl chloride is prepared by polymerisation of monomer vinyl chloride about 80 percent of polymerisation includes suspension polymerisation 12 emulsion polymerisation and 8 bulk polymerisation. Economical versatile polyvinyl chloride pvc or vinyl is used in a variety of applications in the building and construction health care electronics automobile and other sectors in products ranging from piping and siding blood bags and tubing to wire and cable insulation windshield system components and more. Pvc is made by subjecting vinyl chloride to highly reactive compounds known as free radical initiators.

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. The reaction vessel is. For example polyvinyl chloride is an industrial homopolymer synthesized from repeating units of vinyl chloride. Chemical structure of polyvinyl chloride pvc industrial polymers are synthesized from simple compounds joined together to form long chains.
