Abstract

Water-soluble ethylenically unsaturated compounds are polymerized by a process in which, either the compound or compounds are mixed with water and the mixture is emulsified in an organic solvent containing a surface-active agent to form a water-in-oil emulsion, or the water is emulsified in the organic solvent and the compound or compounds are mixed with the emulsion, the amount of compound or compounds being such that, at 30 DEG C., the aqueous mixture would be at least saturated with the compound or compounds; thereafter the monomeric compound or compounds are polymerized in the presence of a polymerization catalyst until a polymeric material in bead form dispersed in an organic solvent is formed. The process is particularly applicable to the formation of homopolymers of acrylamide and copolymers of acrylamide with acrylic acid or dimethylaminoethyl methacrylate. At the end of the polymerization reaction 0.1-5% of alkali hydroxide, based on the weight of polymer, may be added and the surface of the polymer beads thereby hydrolysed at elevated temperature. The preferred catalyst is a redox mixture of cerium ammonium sulphite and sodium sulphate containing an amount of sulphuric acid.
