Addition Polymerization Of Vinyl Chloride

Used in making of acrylic fabrics which.

Addition polymerization of vinyl chloride.

Acrylonitrile vinyl cyanide ch2 ch cn polymer name structure. Notice how every other carbon must have a chlorine attached. Draw a segment of polyvinyl chloride containing three monomer units connected head to tail. This polymerisation reaction proceeds by a free radical mechanism.

Polymerization is a process by which there is a large number of units of an alkene and alkyne which forms a large compound. The structure of vinyl chloride is shown at the right. Additives are used to modify the properties of polyvinyl chloride to make it more useful. 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. Polyvinyl chloride is obtained on addition polymerisation of vinyl chloride. Addition polymerization of phenyl chloride results in the formation of polyvinyl chloride or pvc. The reaction is shown in the graphic on the left.

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. Notice how every other carbon must have a chlorine attached. Addition polymers are formed.

The reaction to make polypropylene h 2 c chch 3 is illustrated in the middle reaction of. Polyvinyl chloride is a white rigid quite brittle solid. 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 chloride suspension polymerization was carried out in a pilot scale reactor to study the effects of different methods of initiator addition on poly.

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. Othertypes of addition polymers. Polyvinyl chloride is a very useful polymer. Nlesc rate data were also used to test the applicapility of the rodel.

About 13 billion kilograms are produced annually. 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. Polycrylonitrile ch2 ch cn n polymer users. Chemical and physical methods were used to observe irregular structures such as branching.

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