Abstract

A process for the bulk or solution polymerization of an ethylenically unsaturated monomer (as defined herein), characterized by being carried out in the presence of a catalyst system consisting of an organic hydroperoxide activated by a sulfur compound of the general formula: **(See formula)** wherein R represents a straight or branched, substituted or simple alkyl group, or with 1 to 12 carbon atoms, or a cycloalkyl group; X represents the chemical equivalent of a metal of the first or second group of the Periodic System or aluminum or represents one of the groupings signified by R, in which case the polymerization is carried out in the additional presence of an alkali metal alcoholate in which the alkyl group has a straight or branched chain and contains from 1 to 6 carbon atoms, or of an alkali metal hydroxide, in solution of an alcohol (Machine-translation by Google Translate, not legally binding)
