    • 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.
    • 本发明涉及滑石增强的聚碳酸酯组合物,其包含:A)聚碳酸酯,聚酯碳酸酯或其混合物,B)任选地,至少一种选自以下组中的一种聚合物:由在乳液聚合方法中生产的接枝聚合物,接枝聚合物 在本体聚合方法中制备,无橡胶的乙烯基均聚物和无橡胶的乙烯基共聚物,C)滑石,D)布朗斯台德酸,以及任选的E)至少一种聚合物添加剂,其中所述组合物不含芳族或部分芳族化合物 聚酯。 与已知的现有技术相比,本发明组合物具有改进的延展性,耐复合和加工(成型)期间的变形耐热性和热稳定性。 本发明还提供了用于生产模制品和双组分结构部件的组合物的用途。
