Addition Polymerization Of Vinyl Chloride

Polymerization of vinyl chloride vc was studied.

Addition polymerization of vinyl chloride.

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. Acrylonitrile vinyl cyanide ch2 ch cn polymer name structure. Used in making of acrylic fabrics which. Polyvinyl chloride is a very useful polymer.

Polyvinyl chloride is a white rigid quite brittle solid. About 13 billion kilograms are produced annually. 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. Nlesc rate data were also used to test the applicapility of the rodel.

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. This polymerisation reaction proceeds by a free radical mechanism. Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene vinyl chloride monomer.

Natural evolution of hcl from vc occurred in the polymerization. Notice how every other carbon must have a chlorine attached. Polycrylonitrile ch2 ch cn n polymer users. The reaction is shown in the graphic on the left.

The structure of vinyl chloride is shown at the right. This alkene undergoes addition polymerization to form polyvinyl chloride pvc a polymer used in pipes and many other products. 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. Othertypes of addition polymers.

Addition polymerization of phenyl chloride results in the formation of polyvinyl chloride or pvc. Suspension polymerization of vinyl chloride using one and two initiator systems. 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. Addition polymers are formed.

The reaction to make polypropylene h 2 c chch 3 is illustrated in the middle reaction of. Polyvinyl chloride is obtained on addition polymerisation of vinyl chloride. Chemical and physical methods were used to observe irregular structures such as branching. Additives are used to modify the properties of polyvinyl chloride to make it more useful.

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 is shown in the graphic on the left. Draw a segment of polyvinyl chloride containing three monomer units connected head to tail.
