Abstract: The invention relates to thermoplastic polyamide moulding compositions with improved toughness at low temperatures consisting of at least 60% by weight of polyamide and from 3 to 35% by weight of graft rubbers from the group comprising diene rubbers and acrylate rubbers, which are produced in that a mixture of the two components is produced in the presence of from 0.01 to 5% by weight of a radical forming agent and the moulding compositions are then heated below the polyamide melting point as far as possible in the absence of oxygen.
