摘要： The invention provides a polycarbonate composition comprising a) a polycarbonate resin, b) a surface-treated calcium carbonate-containing material, wherein the surface-treated calcium carbonate-containing material is obtained by surface-treating a calcium carbonate-containing material with at least one hydrophobizing agent selected from the group consisting of aliphatic-substituted succinic anhydrides, carboxylic acid- and/or anhydride-functional polysiloxanes, and mixtures thereof, c) optionally titanium dioxide, d) optionally one or more additives. Further, the invention provides an article comprising the polycarbonate composition of the invention and a process for preparing the polycarbonate composition of the invention. The invention also provides a use of a surface-treated calcium carbonate-containing material as defined in the application as a filler for a polycarbonate composition. The invention further provides a surface-treated calcium carbonate-containing material, wherein the surface-treated calcium carbonate-containing material is obtained by surface-treating a calcium carbonate-containing material with at least one hydrophobizing agent selected from the group consisting of carboxylic acid- and/or anhydride-functional polysiloxanes.
