Thermoplastic molding composition comprising components A, B, C, D and E: (A) 10 to 40 wt.-% of at least one graft copolymer (A) consisting of 15 to 60 wt.-% of a graft sheath (A2) and 40 to 85 wt.-% of a graft substrate - an agglomerated butadiene rubber latex - (A1), where (A1) and (A2) sum up to 100 wt.-%, obtained by emulsion polymerization of styrene and acrylonitrile in a weight ratio of 95:5 to 65:35 to obtain a graft sheath (A2), it being possible for styrene and/or acrylonitrile to be replaced partially (less than 50 wt.-%) by alpha-methylstyrene, methyl methacrylate or maleic anhydride or mixtures thereof, in the presence of at least one agglomerated butadiene rubber latex (A1) with a median weight particle diameter D 50 of 150 to 800 nm, where the agglomerated rubber latex (A1) is obtained by agglomeration of at least one starting butadiene rubber latex (S-A1) having a median weight particle diameter D 50 of equal to or less than 120 nm, preferably equal to or less than 110 nm; (B) 25 to 50 wt.-% of at least one aromatic polycarbonate; (C) 20 to 40 wt.-% of at least one copolymer (C) of alpha-methylstyrene and acrylonitrile in a weight ratio of from 95:5 to 50:50, it being possible for alpha-methylstyrene and/or acrylonitrile to be partially (less than 50 wt.-%) replaced by methyl methacrylate, maleic anhydride and/or 4-phenylstyrene; (D) 10 to 25 wt.-% of at least one terpolymer (D) of 50 to 84 wt.-% vinylaromatic monomer, 15 to 35 wt.-% α, β ethylenically unsaturated dicarboxylic cyclic anhydride, and 1 to 25 wt.-% C 1 -C 3 -alkyl-(meth)acrylate; (E) 0.3 to 5 wt.-% of further additives and/or processing aids (E); where the components A, B, C, D and E, sum to 100 wt.-%. (A) 10 to 40 wt.-% of at least one graft copolymer (A) consisting of 15 to 60 wt.-% of a graft sheath (A2) and 40 to 85 wt.-% of a graft substrate - an agglomerated butadiene rubber latex - (A1), where (A1) and (A2) sum up to 100 wt.-%, obtained by emulsion polymerization of styrene and acrylonitrile in a weight ratio of 95:5 to 65:35 to obtain a graft sheath (A2), it being possible for styrene and/or acrylonitrile to be replaced partially (less than 50 wt.-%) by alpha-methylstyrene, methyl methacrylate or maleic anhydride or mixtures thereof, in the presence of at least one agglomerated butadiene rubber latex (A1) with a median weight particle diameter D 50 of 150 to 800 nm, where the agglomerated rubber latex (A1) is obtained by agglomeration of at least one starting butadiene rubber latex (S-A1) having a median weight particle diameter D 50 of equal to or less than 120 nm, preferably equal to or less than 110 nm; (B) 25 to 50 wt.-% of at least one aromatic polycarbonate; (C) 20 to 40 wt.-% of at least one copolymer (C) of alpha-methylstyrene and acrylonitrile in a weight ratio of from 95:5 to 50:50, it being possible for alpha-methylstyrene and/or acrylonitrile to be partially (less than 50 wt.-%) replaced by methyl methacrylate, maleic anhydride and/or 4-phenylstyrene; (D) 10 to 25 wt.-% of at least one terpolymer (D) of 50 to 84 wt.-% vinylaromatic monomer, 15 to 35 wt.-% α, β ethylenically unsaturated dicarboxylic cyclic anhydride, and 1 to 25 wt.-% C 1 -C 3 -alkyl-(meth)acrylate; (E) 0.3 to 5 wt.-% of further additives and/or processing aids (E); <EOS>
