    摘要： The invention relates to a polymer composition comprising 5 to 79 wt.% of a graft copolymer of vinyl aromatic monomer units and monomer units chosen from the group of C 1 -C 4 alkyl methacrylates, C 1 -C 4 alkyl acrylates, methacrylonitrile and acrylonitrile on a rubber, 90 to 20 wt.% of a thermoplastic polymer with polar groups, and 1 to 50 wt.% of a terpolymer comprising a vinyl aromatic monomer, at least one monomer chosen from the group of C 1 -C 4 alkyl methacrylates, C 1 -C 4 alkyl acrylates, methacrylonitrile and acrylonitrile, and 0.2 to 5 mol% of an α,β-unsaturated compound containing dicarboxylic anhydride, the wt.% of components (A), (B) and (C) being relative to the total weight of components (A), (B) and (C), characterized in that the molar mass of component (C) is comprised between 160,000 g/mol and 230,000 g/mol. The polymer composition has excellent mechanical properties, in particular a high impact resistance at low temperatures.
