Abstract

The invention relates to compatible blends of 94 to 10% by weight aromatic poly(ester) carbonates or polycarbonates, 5 to 70% by weight polyamides and 1 to 20% by weight ester-functional (meth)acrylate polymers and, optionally, elastomers in typical modifying quantities, to a process for the production of these blends and to their use for the production of moldings.
