Preparation of highly heat-resistant (co)polycarbonates by the transesterification method

The present invention relates to a melt transesterification process for the production of (co)polycarbonates from diaryl carbonates and cycloalkylidene diphenols, which process comprises the addition of a monohydroxyaryl compound in an amount of 5.0 to 20.0 wt.-%, based on the total mass of the reac...

Zusammenfassung:	The present invention relates to a melt transesterification process for the production of (co)polycarbonates from diaryl carbonates and cycloalkylidene diphenols, which process comprises the addition of a monohydroxyaryl compound in an amount of 5.0 to 20.0 wt.-%, based on the total mass of the reaction mixture. The invention further relates to a (co)polycarbonate obtained by the process.
