Vinyl Chloride Repeat Unit

Vinylidene chloride chemical formula ch 2 ccl 2 polymer repeating unit structure ch 2 ccl 2 can be made directly from ethylene and chlorine or by the further chlorination of vinyl chloride with subsequent removal of hydrogen chloride by alkali treatment.

Vinyl chloride repeat unit.

It is polymerized in suspension or emulsion processes using free radical. About 13 billion kilograms are produced annually. Use table 4 3 p110 textbook. Molar volume v m.
