Abstract

Polyvinyl chloride is made by polymerizing in bulk, vinyl chloride at a temperature below -30 DEG C. in the presence of a catalyst system comprising an organo-metallic compound of Groups IIa or IIIa, of the Periodic System (which is not a boron trialkyl) and a per-ester or hydroperoxide in which one of the oxygen atoms of the peroxy group is directly attached to a tertiary carbon atom. The percompound may be t-butyl, or cumene hydroperoxide, t-butyl perlaurate, t-butyl peracetate, t-butyl perbenzoate, or t-butyl triperborate. Specified organo-metallic compounds are ethyl magnesium bromide, t-butyl magnesium chloride, diethyl boron fluoride, diethyl aluminium chloride, di-isobutyl aluminium hydride, dibutyl boric acid anhydride, diethyl beryllium, triethyl aluminium, and triethyl indium. U.S.A. Specification 2,160,935 is referred to.
