Polymer Of Vinyl Chloride Example

Chemical structure of polyvinyl chloride pvc industrial polymers are synthesized from simple compounds joined together to form long chains.
Polymer of vinyl chloride example. A polymer made from only one type of monomer. Monomeric vinyl chloride is polymerized in a solution of high molecular weight polytetrahydrofuran therein to produce a graftpolymer which is transparent and has high impact strength. 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. 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.
Monomers can be combined in various repeating patterns to form different types of polymers. And adding 0 005 parts by weight of eugenol. For example polyvinyl chloride is an industrial homopolymer synthesized from repeating units of vinyl chloride. A vinyl chloride based polymer was obtained by the same method described in example 1 except for performing a reaction while maintaining the polymerization temperature at 47 c.
The building block of polymers. 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 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. Rigid sometimes abbreviated as rpvc and flexible.
The reaction vessel is. 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. A polymer that is synthesized naturally by a plant or organism. A method of preparing a clear high impact strength vinyl chloride polymer is described.
A polymer of vinyl chloride. A member of the family vinyl resin used in soft flexible films for food packaging and in molded rigid products such as pipes fibers upholstery and bristles. It is tasteless odorless and insoluble in most organic solvents. 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.
A vinyl chloride based polymer was obtained by the same method described in example 3 except for. A graft polymer product having improved transparency and impact strength is also described. Vinyl chloride ch2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst. Vcm and water are introduced into the reactor and a polymerization initiator along with other additives.
Pvc comes in two basic forms.
