Abstract
Process for the preparation of polymers with uniform molecular weight, from polymerizable material comprising at least one compound containing a group (see formula) characterized in that the polymerization of said polymerizable material in an aqueous medium at a pH not exceeding approximately 4.0 is verified, using an oxidation-reduction catalyst system, comprising from 0.1 to 3% approximately in weight of chlorate ions and approximately 0.1 to 9% by weight of sulfoxy ions, a variation of the percentage of conversion of said polymerizable material into said polymer being effected by decreasing or increasing, respectively, the ratio between molar equivalents of the ions sulfoxyl and the polymerizable material, together with a decrease or increase, respectively, in the ratio between molar equivalents of chlorate ions and the polymerizable material, which is greater than the decrease or increase in the ratio between molar equivalents of sulfoxyl ions and the polymerizable material .
