Abstract

The invention relates to compatible blends having good surfaces of aromatic polycarbonates or poly(ester) carbonates and polyamides and, optionally, graft polymers and typical additives with addition of polymers containing sulfonamide units as compatibilizers, to a process for the production of these blends and to their use for the production of moldings having good surface properties.
