Abstract: Aqueous polymer dispersions and processes for preparing them are described. The polymer dispersions can be obtained by free-radically initiated emulsion polymerization of from 19.9 to 80 parts by weight of vinylaromatic compounds, from 19.9 to 80 parts by weight of acrylate monomers selected from among C1-C10-alkyl acrylates and C1-C10-alkyl methacrylates, from 0.1 to 10 parts by weight of ethylenically unsaturated acids and from 0 to 20 parts by weight of other ethylenically unsaturated monomers, wherein the emulsion polymerization is carried out in an aqueous medium in the presence of free-radical-forming initiators, seed latex and at least one carbohydrate compound in the form of a degraded starch. The polymer dispersions are particularly suitable for producing paper coating compositions.
