    摘要： Moulding compositions based on ABS-graft polymers, containing:A. 5 to 70 parts, by weight of a graft polymer obtained by grafting 20 to 60 parts by weight of a mixture of styrene and acrylonitrile in a ratio, by weight, of 95 : 5 to 60 : 40 onto 80 to 40 parts, by weight, of polybutadiene or a butadiene copolymer with a butadiene content of > 30% with an average particle diameter of 0.26 to 0.65 .mu. and a grafting degree of 0.15 to 0.7;B. 0 to 50 parts, by weight, of a graft polymer obtained by polymerizing 40 to 60 parts, by weight, of a mixture of styrene and acrylonitrile in a ratio, by weight, of 95 : 5 to 60 : 40 onto 60 to 40 parts, by weight, of polybutadiene or a butadiene copolymer with a butadiene content of more than 30%, with an average particle diameter of from 0.05 to 0.25 .mu. and a grafting degree of 0.4 to 0.9; andC. 25 to 95 parts, by weight, of a copolymer of styrene and/or .alpha.-methyl styrene on the one hand and acrylonitrile on the other hand in a ratio by weight, of 80 : 20 to 60 : 40 with an average molecular weight M.sub.w (weight average) of from 50,000 to 200,000 and a molecular heterogeneity U of 4.5 to 1.0; such thatD. the ratios, by weight, of styrene (including .alpha.-methyl styrene if present) to acrylonitrile satisfy the following conditions: ##EQU1##

    摘要： Interpolymers of aromatic polyesters and cross-linked (or partially cross-linked) rubbers and a process for their production in which a mixture of a cross-linked rubber in latex form containing reactive groups and an aqueous solution of an alkali metal or alkaline earth metal diphenolate is reacted with a solution of a dicarboxylic acid halide and/or a carbonyl halide in a water-immiscible solvent so that an aromatic polyester forms at the water/organic solvent phase boundary, which polyester goes over into the organic phase and the rubber at the same time also goes into the organic phase. The interpolymer of rubber and organic polyester thus formed is suitable for the production of moulded articles of all kinds by the methods of thermoplastic shaping such as extrusion and injection moulding.
