A method of obtaining homopolymers and / or copolymers, in aqueous solution, from ethylenically unsaturated monomers, characterized by the use of compounds that contain a phosphorus atom with an oxidation level of less than 5, added in a molar amount ranging from 0.005 and 0.49 phosphorous atoms per mole of unsaturation to be polymerized, in the presence of hydrogen peroxide and in the absence of any agent that could decompose hydrogen peroxide into free radicals such as metals or metal salts as well as in the absence of any other free radical generator and in the absence of any persal and / or any other transfer agent. |
