Abstract
Vinyl chloride is polymerised at atmospheric pressure in presence of a catalyst of general formula B2RmHp, wherein R is alkyl, p is a whole number equal to 1 or more, and m + p = 6, e.g. diborane or dinethyldiborane. The reaction may be effected in bulk or in presence of an inert organic medium such as n-hexane. In examples reaction temperatures of 0 DEG and -40 DEG C. are used.
