    摘要： The invention relates to compositions, containing A) 70 to 95 parts by weight of at least one polymer selected from the group comprising aromatic polycarbonate and aromatic polyester carbonate, B) 1 to 10 parts by weight of a mixture containing at least one polybutadiene-containing vinyl (co)polymer and at least one polybutadiene-free vinyl (co)polymer, C) 1 to 20 parts by weight of at least one flameproofing agent containing phosphorus, selected from the group comprising phosphonate amines, phosphazenes, and monomeric and oligomeric phosphoric acid and phosphonic acid esters of general formula (V), wherein R

    12 aralkyl, n means, independently of each other, 0 or 1, q means 0 to 30, X means a polynuclear aromatic group having 12 to 30 C atoms, or a linear or branched aliphatic group having 2 to 30 C atoms which can be OH-substituted and contain up to 8 ether bonds, D) 0.1 to 20.0 parts by weight (with respect to the sum of components A to C) of at least one polymer additive, wherein the polybutadiene content is 0.5 to 5.5 wt% with respect to the sum of the parts by weight of components A to C, and wherein the total content of butadiene-free vinyl co(polymer) from component B is 0.5 to 5.0 wt% with respect to the sum of components A to C, and wherein the compositions are free of thermoplastic polyesters such as polyalkylene terephthalates, and wherein the sum of the parts by weight of components A, B, and C in the polycarbonate composition is standardized to 100. The invention further relates to composite parts composed of said compositions and of a polyurethane layer, which composite parts are distinguished by improved adhesion between the two layers, and to a method for producing the composite parts.
