| titleOfInvention | Polycarbonate compositions with improved optical and thermal properties |
| abstract | Process for the preparation of polycarbonates containing structural units of general formula (I): ** Formula ** with R1 and R2 independently of each other H, halogen, C1-C8 alkyl, C5-C6 cycloalkyl, C6-C10 aryl and C7 arylalkyl - C12, with m equal to 4 or 5, with R3 and R4 that can be freely selected for each X and are independently from each other H or C1-C8 alkyl, with X equal to carbon, according to the interface procedure or procedure of melt transesterification, characterized in that the bisphenols used for the preparation of the polycarbonate have a sulfur content of less than 1.5 ppm. |
