摘要：
A thermoplastic molding composition having improved flow, toughness. and heat distortion comprising a polymer mixture of (A) 25 to 95% by weight of a graft polymer of 70 to 30% by weight of a mixture of styrene (95 to 50% by weight) and acrylonitrile (5 to 50% by weight) on 30 to 70% by weight of an EPDM-rubber, and (B) 50 to 75% by weight of a terpolymer of acrylonitrile, maleic acid anhydride and styrene, the terpolymer containing 10 to 30 parts by weight of acrylonitrile, 7.5 to 15 parts by weight of maleic acid anhydride, and 82.5 to 55 parts by weight of styrene in copolymerised form.
