The present invention relates to compositions comprising A) 30 to 45 parts by weight of at least one polymer selected from the group consisting of aromatic polycarbonate and aromatic polyester carbonate, B) 32 to 54 parts by weight of at least one polyalkylene terephthalate, preferably a polybutylene terephthalate, C) 16 to 23 parts by weight of at least one mixture comprising at least one polybutadiene-containing vinyl (co)polymer and at least one polybutadiene-free vinyl (co)polymer, D) 0.1 to 20.0 parts by weight (based in each case on the sum total of components A to C) of at least one polymer additive, where the polybutadiene content based on the sum total of the parts by weight of components A to C is 8% to 18% by weight, and where the total content of butadiene-free vinyl (co)polymer from component C based on the sum total of the parts by weight of components A to C is 3% to 12% by weight, and where the sum total of the parts by weight of components A to C in the polycarbonate composition is normalized to 100, and to composite components formed from these compositions and a polyurethane layer, which are notable for improved adhesion between the two layers, and to a process for producing the composite components. |
