Abstract

A thermoplastic molding composition containing talc is disclosed. The composition wherein talc has a median particle size of less than 1000 nm further contains a polycarbonate and/or polyester-carbonate, and a graft polymer having as graft base a rubber having a glass transition temperature of below about 10° C. is suitable for preparing molded articles having improved mechanical properties, such as weld line strength, elongation at break and toughness at low temperatures.
