The present invention relates to compositions comprising A)? 55 to 75 parts by weight of at least one polymer selected from aromatic polycarbonates and aromatic polyester carbonates, B)? 25 to 45 parts by weight of at least one mixture comprising at least one butadiene-based graft polymer prepared by emulsion, suspension or solution polymerization and at least one polybutadiene-free vinyl (co)polymer, C)? 0.1 to 20.0 parts by weight? (based on the sum of components A and B, respectively)? at least one polymer additive, wherein the polybutadiene content is 10 to 20% by weight based on the sum of the parts by weight of components A and B, and wherein the butadiene-free vinyl of component B (total ) The total content of the polymer is 12 to 23% by weight based on the sum of the parts by weight of components A and B, and wherein the sum of the parts by weight of components A and B in the polycarbonate composition is normalized to 100; and from the Composite components composed of said composition and a polyurethane layer, characterized by improved adhesion between said two layers; and methods of preparing such composite components. |
