A Polymer Of Vinyl Chloride Example

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.

A polymer of vinyl chloride example.

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. Polyvinyl fluoride pvf vinyl acetate. Vinyl chloride c 2 h 3 cl is the monomer link in the polyvinyl chloride chain. Major industrial polymers major industrial polymers polyvinyl chloride pvc.

Example of resulting polymer vinyl chloride. What is a polymer of vinyl chloride. And adding 0 005 parts by weight of eugenol. Copolymers are made with vinyl acetate and ethylene to improve rheology properties.

A vinyl chloride based polymer was obtained by the same method described in example 3 except for. Polyvinyl acetate pvac many vinylidene and vinylene compounds polymerize in the same manner. 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. Vinyl chloride may be represented by the structural formula.

The reaction vessel is. An example would be useful. Plasticized pvc polyvinyl chloride so boots and coats and stuff like that or unplasticized pvc for sidings and windows etc. About 13 billion kilograms are produced annually.

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. It is highly susceptible to uv and high temperature degradation and stabilizers see stabilizers in the polymer additives section are commonly added.

Those polymers are analogously referred to as polyvinylidenes and polyvinylenes reflecting the monomeric precursors.

Two main commercail available polmers. 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. Polyvinyl chloride pvc vinyl fluoride. Vinyl chloride ch2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst.

Poly vinyl chloride is often highly plasticized to improve rheology for melt processing. Vcm and water are introduced into the reactor and a polymerization initiator along with other additives.
