Abstract
Described are aqueous polymer dispersions and methods of making them. The polymer dispersions are obtainable by free-radically initiated emulsion polymerization of 19.9 to 80 parts by weight of vinylaromatic compounds, 19.9 to 80 parts by weight of acrylate monomers selected from C1-C10 alkyl acrylates and C1-C10 alkyl methacrylates, 0.1 to 10 parts by weight of ethylenically unsaturated acids, and 0 to 20 parts by weight of other ethylenically unsaturated monomers, wherein the emulsion polymerization is effected in an aqueous medium in the presence of free-radical initiators, seed latex and also at least one carbohydrate compound in the form of a degraded starch. The polymer dispersions are particularly useful in the manufacture of paper coating slips.
