A process for the preparation of homopolymers and / or copolymers of ethylenically unsaturated monomers in an aqueous solution using a compound containing a phosphorus atom in an oxidation degree of less than 5 in an amount of 0.005 to 0.49 phosphorus atom per mole of unsaturation to be polymerized in the absence of all peroxide degrading agents hydrogen to free radicals, and in the absence of a carrier. Also described are homopolymers and / or copolymers of ethylenically unsaturated monomers in an aqueous solution having a very low residual monomer content, obtained by this process, and their use. |
