Abstract

The present invention relates to the use of specific graft polymers to improve the petroleum-resistance of thermoplastic, aromatic polycarbonates and/or polyester carbonates, mixtures of polycarbonate and/or polyester carbonate with these specific graft polymers and, if appropriate, with other thermoplastic resins and/or with effective amounts of customary additives, and in addition to a process for the production of these mixtures.
