Abstract: The invention relates to thermally stable and UV-stable polyamide molding compounds containing colloidal copper formed in situ and to a process for their production.

Abstract: The present invention relates to easily processable polyamide moulding materials with very good mechanical and electrical properties based on calcium magnesium carbonate hydrate as the flame-retardant additive.

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.

Abstract: The invention relates to improved polymer blends of polyamides and vinyl polymers containing sulfonamide structural units. Polyamide molding compounds having reduced water absorption and improved dimensional stability coupled with good mechanical properties, such as impact strength and rigidity, minimal discoloration, high heat resistance and migration resistance, are thus obtained.

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.
