POLYCARBONATE COMPOSITIONS CONTAINING FILLERS AND TRIACYLGLYCEROL CONTAINING EPOXY GROUPS

Abstract

The invention relates to carbon fiber-containing polycarbonate compositions, the flowability of which is significantly improved by adding epoxidized triacylglycerols, for example as a constituent of epoxidized soy bean oil. In addition to the very high flowability, the compositions according to the invention have a high rigidity.

[0144] Comparative examples C.sub.1 and C.sub.2, which do not contain component C, have a much lower flowability than examples 1 to 4 and 5 to 8. This is shown both in the MVR values and in the shear viscosities at different measurement temperatures and different shear rates.

[0145] The very good flame retardancy properties and the good mechanical properties, determined by tensile test, are retained. The flowability of the molten compositions increases as the proportion of component C rises. A comparable situation can be ascertained for the following series of tests, the compositions starting from table 5 being free of flame retardant.
