1. A thermoplastic molding composition consisting essentially of the following components:
A) 3 to 77 wt % of one or more styrene copolymers, as component A, B) 15 to 89 wt % of one or more polyamides, as component B, C) 5 to 50 wt % of two or more graft rubbers without olefinic double bonds in the rubber phase, as component C, wherein the graft base core of the two or more graft rubbers is based on elastomers selected from the group consisting of elastomers based on C1 to C8 alkyl esters of acrylic acid, ethylene/propylene, or siloxanes,
wherein the two or more graft rubbers comprise a first graft rubber C1 and a second graft rubber C2, wherein:the first graft rubber C1 has a graft shell comprising 60 to 95 wt % of styrene or α-methylstyrene or mixtures thereof and 5 to 40 wt % of at least one unsaturated nitrile, andthe second graft rubber C2 has a graft shell based on acrylates or methacrylates, and a fraction of 0.1 to 2 wt % of a monomer containing epoxide groups, in the outer graft shell, D) 1 to 25 wt % of a terpolymer of styrene, acrylonitrile, and maleic anhydride, as component D, E) 2 to 30 wt % of rubber based on olefinic monomers, as component E, F) 0 to 50 wt % of fibrous or particulate filler or mixtures thereof, as component F, G) 0 to 40% of further adjuvants, as component G,the wt % being based in each case on the total weight of components A to G and together making 100 wt %. |
