    Abstract: Addition of special types of talc of mean particle diameter less than about 1000 nm to polycarbonate/ABS blends a clear increase in breaking elongation, ductility, and binder bond strength can be obtained without affecting the Young's Modulus compared with comparable molding compositions containing conventional types of talc. A new polycarbonate composition contains: (A) at least one aromatic polycarbonate and/or polyester carbonate; (B) at least one graft polymerisate from 5-95 wt.% of a mixture containing (wt.%): vinyl aromatics and/nucleus substituted vinyl aromatics and/or methacrylic acid 1-8C alkyl ester (50-99), vinyl cyanide and/or (meth)acrylic acid 1-8C alkyl ester and/or a derivative of unsaturated carboxylic acids (1-50), at least one graft base of glass transition temperature below about 10 deg C (95-5), and (C) at least one talc of mean particle size less than 1000 nm. Independent claims are included for: (1) preparation of the composition in which components (A) to (C) and optionally other components are mixed at 200-300 deg C to give conventional aggregates, kneaded, extruded, melt compounded, or melt extruded; and (2) a profiled body containing the composition.
