Thermoplastic molding compositions based on styrene copolymers and polyamides

The thermoplastic molding composition composed of A) a polyamide having terminal amino groups or carboxylic or a mixture of these end groups, B) a mixture of at least two graft copolymers containing, in each case a rubber base graft and a graft shell based on an unsaturated monomer, which are distinguished from each other by the rubber content of at least 5% by weight, C) a rubber-free copolymer containing, c1) at least 30 % by weight of units derived from a vinylaromatic monomer, based on the total weight of all units present in C), c2) units derived from a monomer containing a functional group which can react with the end groups of the polyamide a) and c3) units derived from a monomer containing no functional group, which reacts with the terminal groups of the polyamide a) and, moreover, if desired D) a free matrix polymer rubber, E) a ba compound jo molecular weight, containing a dicarboxylic anhydride group and F) an additive or a mixture of various additives.
