Abstract
A thermoplastic molding composition suitable for molding articles that feature good mechanical properties, good flowability and improved flame, heat and UV resistance is disclosed. The composition contains polycarbonate and/or polyestercarbonate, calcined talc, a graft polymer and at least one oligomeric phosphoric acid esters conforming to formula (I), 1 wherein R1, R2, R3 and R4 independently one of the others denote C1 to C8 alkyl, C5 to C6 cycloalkyl, C6 to C20 aryl or C7 to C12 aralkyl, n independently one of the others denotes 0 or 1 q denotes 0.8 to 30 and X denotes a member selected from the group consisting of mononuclear or polynuclear aromatic radical having 6 to 30 C atoms, and linear or branched aliphatic radical having 2 to 30 C atoms.
