    Abstract: A thermoplastic molding composition composed of, based on the total of A, B, C and D, 40-95% by weight of a copolymer A of, based on A, 90-95% by weight of styrene and/or its derivatives and 10-50% by weight of acrylonitrile, optionally up to 50% by weight of a graft copolymer B of 20-80% by weight of a monomer mixture of either styrene/acrylonitrile in the ration from 9:1 to 4:6 or styrene/acrylonitrile/methylacrylate in the ration from 19:1:1 to 8:6:6 onto 80-20% by weight of an elastomer based on butadiene or acrylic ester as grafting base, graft copolymerization being effected in either emulsion or solution, 1-50% by weight of a reinforcing glass fiber material C and 0.1-50% by weight of a terpolymer D of styrene, methyl methacrylate and maleic anhydride composed of 1-15% by weight each of styrene and maleic anhydride and a styrene/maleic anhydride ratio of from 5:1 to 1:5, and methyl methacrylate.
