Addition Polymerization Of Vinyl Chloride

This alkene undergoes addition polymerization to form polyvinyl chloride pvc a polymer used in pipes and many other products.

Addition polymerization of vinyl chloride. Polymerization is a process by which there is a large number of units of an alkene and alkyne which forms a large compound. The reaction to make polypropylene h 2 c chch 3 is illustrated in the middle reaction of. 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. Notice how every other carbon must have a chlorine attached.

Acrylonitrile vinyl cyanide ch2 ch cn polymer name structure. 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. Suspension polymerization of vinyl chloride using one and two initiator systems. The reaction is shown in the graphic on the left.

Nlesc rate data were also used to test the applicapility of the rodel. Draw a segment of polyvinyl chloride containing three monomer units connected head to tail. The reaction is shown in the graphic on the left. Addition polymers are formed.

The structure of vinyl chloride is shown at the right. Natural evolution of hcl from vc occurred in the polymerization. Polyvinyl chloride is obtained on addition polymerisation of vinyl chloride. Used in making of acrylic fabrics which.

This polymerisation reaction proceeds by a free radical mechanism. Polyvinyl chloride is a very useful polymer. Addition polymerization of phenyl chloride results in the formation of polyvinyl chloride or pvc. 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.

Polymerization of vinyl chloride vc was studied. 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. About 13 billion kilograms are produced annually. 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.

Polycrylonitrile ch2 ch cn n polymer users. Othertypes of addition polymers. Chemical and physical methods were used to observe irregular structures such as branching. 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.

Polyvinyl chloride is a white rigid quite brittle solid. Notice how every other carbon must have a chlorine attached. 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.
