| titleOfInvention | Process for producing polycarbonate by melt transesterification |
| abstract | The present invention relates to a method for producing a polycarbonate by a melt transesterification method, a polycarbonate having a low electrostatic charge accumulation obtained by this method, and a molded article or extrudate containing the polycarbonate, particularly an optical data storage device or a diffuser disk. . A process for producing a polycarbonate by a melt transesterification method comprising reacting at least one dihydroxyaryl compound and at least one diaryl carbonate in a multistage process in the presence of at least one catalyst. At least one inhibitor is added to the melt before the final reaction stage, and one or more aliphatic hydroxydicarboxylic acids and / or hydroxypolycarboxylic acids or their compounds in the final reaction stage or after the final reaction stage. Achieved by the polycarbonate manufacturing process with the addition of derivatives. [Selection figure] None |
