The invention relates to talcum-reinforced polycarbonate compositions comprising: A) a polycarbonate, polyester carbonate or a mixture thereof, B) optionally, at least one polymer selected from one of the group consisting of graft polymer produced in an emulsion polymerisation process, graft polymer produced in a bulk polymerisation process, rubber-free vinyl homopolymer and rubber-free vinyl copolymer, C) talcum, D) a Brönstedt acid, and optionally E) at least one polymer additive, and wherein the composition is free of aromatic or partially aromatic polyesters. Compared to the known prior art the inventive compositions have an improved ductility, thermal resistance towards deformation and thermal stability during compounding and processing (molding). The invention also provides for the use of the composition for the production of molded articles and two-component structural parts.
A composition comprising
A composition comprising a linear polycarbonate based on bisphenol A, an ABS polymer, optionally an SAN copolymer, talcum, either anhydrous citric acid or terephthalic acid, and pentaerythritol tetrastearate.
A talcum-filled, polycarbonate compositions comprising at least one Brönsted acid.
