Abstract: An aqueous polymer dispersion having a solids volume concentration of at least 50% by volume which is obtainable by polymerisation of monomers by free-radical aqueous emulsion polymerisation with addition of at least two starting polymer dispersions, of which one is both particularly finely divided and contains coarse polymer particles.

Abstract: Impact-resistant thermoplastic molding materials are produced by graft polymerization of styrene, acrylonirtils and/or methyl methacrylate onto a rubber latex. The rubber latex employed has a mean particle size of less than 0.15 .mu. and is agglomerated partially, before grafting, by addition of an acrylic ester polymer dispersion. The molding materials obtained exhibit an optimum combination of mechanical properties obtained be converted to shaped articles by extrusion, deep-drawing or injection molding.
