摘要:
Thermoplastic, high-impact moulding compositions of (A) 5 to 80 parts by weight of a graft product of 70 to 30% by weight of a mixture of an aromatic vinyl compound and acrylonitrile and/or methacrylonitrile on 30 to 70% by weight of a rubber having a glass transition temperature of below -10.degree. as the graft base and (B) 20 to 95 parts by weight of a terpolymer of styrene and/or .alpha.-methylstyrene, p-methylstyrene and acrylonitrile and/or methacrylonitrile, the terpolymer having been produced by mass polymerization.
