Process for the preparation of an aqueous dispersion of a polymerized A by polymerization in aqueous emulsion, initiated with radicals, of ethylenically unsaturated monomers in the presence of at least one auxiliary dispersion agent and at least one radical initiator, characterized in that polymerization is used for polymerization - 0.1 to 5% by weight of acrylamide and / or methacrylamide (monomer A1), - 0.1 to 15% by weight of at least one ethylenically unsaturated C3 to C6 mono- or dicarboxylic acid (monomer A2), - 0 , 1 to 10% by weight of at least one ethylenically unsaturated compound, which has at least one oxyranyl group or an oxetanyl group (monomer A3), and - 70 to 99.7% by weight of at least one other ethylenically unsaturated compound, which It is copolymerizable with monomers A1 to A3 (monomer A4), where the amounts of monomer A1 to A4 give 100% by weight. |
