Addition Polymerization Of Vinyl Chloride

Parts i and i i also include a rather extensive review of pvc r tecjmology and the variolls models that have been publ ishcd for i1klss and suspension imlymerizatiqn of vinyl chloride.

Addition polymerization of vinyl chloride.

Polyvinyl chloride is obtained on addition polymerisation of vinyl chloride. This polymerisation reaction proceeds by a free radical mechanism. Addition polymers are formed. Nlesc rate data were also used to test the applicapility of the rodel.

The reaction is shown in the graphic on the left. Vc vc αd 1 vc β βd 2 and vc d 3 were used to study the reactivities of the hydrogen atoms in the polymerization and the β hydrogen atoms contributed to the chain transfer. Othertypes of addition polymers. Notice how every other carbon must have a chlorine attached.

Additives are used to modify the properties of polyvinyl chloride to make it more useful. Polymerization of vinyl chloride vc was studied. Polyvinyl chloride is a very useful polymer. About 13 billion kilograms are produced annually.

Used in making of acrylic fabrics which. Addition polymerization of phenyl chloride results in the formation of polyvinyl chloride or pvc. 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. The reaction is shown in the graphic on the left.

Natural evolution of hcl from vc occurred in the polymerization. Vinyl chloride suspension polymerization was carried out in a pilot scale reactor to study the effects of different methods of initiator addition on poly. Polymerization is a process by which there is a large number of units of an alkene and alkyne which forms a large compound. Pvc polyvinyl chloride which is found in plastic wrap simulated leather water pipes and garden hoses is formed from vinyl chloride h 2 c chcl.

When unsaturated carbon organic molecules reactto form a long chain polymer molecule and no small molewles or atoms are eliminatedduring the reaction monomer name structure. Notice how every other carbon must have a chlorine attached. Polycrylonitrile ch2 ch cn n polymer users. Acrylonitrile vinyl cyanide ch2 ch cn polymer name structure.

Draw a segment of polyvinyl chloride containing three monomer units connected head to tail. The structure of vinyl chloride is shown at the right. Polyvinyl chloride is a white rigid quite brittle solid. Chemical and physical methods were used to observe irregular structures such as branching.

Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer. Journal of vinyl and additive technology is a peer reviewed technical publication for new work in the fields of polymer modifiers and additives vinyl polymers and selected review papers. This alkene undergoes addition polymerization to form polyvinyl chloride pvc a polymer used in pipes and many other products.
