Abstract

A mineral-filled, impact-resistant thermoplastic molding composition is disclosed. The composition contains at least one resin selected from the group consisting of polycarbonate and polyester carbonate B) impact resistance modifier, and C) wollastonite having carbon content greater than 0.1% relative to the weight of the wollastonite as determined by elemental analysis. Exhibiting high modulus of elasticity and a good toughness, in particular also at low temperatures, the composition is suitable for car body external applications.
