THERMOPLASTIC COMPOSITIONS WITH GOOD MECHANICAL PROPERTIES

The invention relates to compositions for the production of thermoplastic moulding materials, where the compositions comprise the following constituents:A) at least one polymer selected from the group consisting of aromatic polycarbonate, aromatic polyester carbonate and polyester,B) at least one anhydride-functionalized with ethylene-α-olefin-copolymer or ethylene-α-olefin terpolymer,where the weight-average molar mass of component B, determined by high-temperature gel permeation chromatography using ortho-dichlorobenzene as solvent against polystyrene standards is from 50000 to 500000 g/mol,and also to a process for the production of the moulding materials, to the moulding materials themselves, to the use of the compositions or moulding materials for the production of mouldings, and to the mouldings themselves.
