| titleOfInvention | Polycarbonate molding compositions |
| abstract | The invention relates to talcum-reinforced polycarbonate compositions containing A) 10 to 100 parts by weight, preferably 80 to 100 parts by weight, particularly preferably 85 to 100 parts by weight, and particularly also 100 parts by weight, relative to the sum of components A and B, of a polycarbonate, a polyester carbonate, or a mixture thereof; B) 0 to 90 parts by weight, preferably 0 to 20 parts by weight, particularly preferably 0 to 15 parts by weight and particularly also 0 parts by weight, relative to the sum of components A and B, of a polymer selected from at least one of the group comprising grafted polymers prepared by an emulsion polymerization, grafted polymers prepared by mass polymerization, rubber-free vinyl homopolymers, and rubber-free vinyl copolymers; C) 7 to 30% by weight, preferably 7 to 22% by weight, particularly preferably 7 to 15% by weight, and particularly preferably 7 to 12% by weight, relative to the total composition, of talcum, preferably a talcum with an Al2O3 content of < 1.0% by weight, particularly a talcum with an average particle diameter d50 of < 2 mm; D) 0.01 to 1% by weight, preferably 0.01 to 0.5% by weight, particularly preferably 0.02 to 0.4% by weight, relative to the total composition, of a Bronstedt acid; E) 0 to 20% by weight, preferably 0 to 5% by weight, and particularly preferably 0.2 to 4% by weight, of at least one polymer additive, wherein the composition is free of aromatic or partially aromatic polyesters, wherein the sum of the percentages by weight of components A and B in the total composition is calculated from the difference between 100% by weight and the sum of the percentages by weight of components C, D, and E, and wherein the total composition is understood to be the sum of the percentages by weight of all the components A + B + C + D + E = 100% by weight. Compared to the known prior art, the talcum-reinforced polycarbonate compositions have an improved ductility, heat distortion stability, and thermal stability during compounding and processing (molding). Additional subjects of the invention relate to the use of the composition for the production of molded objects and two-component construction elements. |
