ABSTRACT:
Thermoplastic molding compositions, comprisingA) from 10 to 95% by weight of a thermoplastic polyamide,B) from 5 to 90% by weight of an acrylate rubber, obtainable via free-radical-initiated aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one dispersing agent and of at least one free-radical initiator, where the emulsion polymerization usesfrom 1 to 50% by weight of an alkene having from 5 to 12 carbon atoms [monomer A], andfrom 50 to 99% by weight of an ester based on an α,β-monoethylenically unsaturated mono- or dicarboxylic acid having from 3 to 6 carbon atoms and on an alkanol having from 1 to 12 carbon atoms [monomer B], and also, if appropriate,up to 10% by weight of an α,β-monoethylenically unsaturated mono- or dicarboxylic acid having from 3 to 6 carbon atoms and/or its amide [monomer C], andup to 30% by weight of an α,β-ethylenically unsaturated compound different from the monomers A to C [monomer D],and the monomers A to D give a total of 100% by weight,C) from 0 to 40% by weight of a copolymer which comprises vinylaromatic monomer units,D) from 0 to 70% by weight of further additives,where the total of the percentages by weight of A) to D) is 100%.
