| titleOfInvention | Process for the preparation of diaryl and polycarbonates |
| abstract | ThenThe invention relates to a process for the preparation of diaryl andnPolycarbonates, wherein dialkyl carbonate is reacted with Borsäuretriarylester andneither the mixture thus obtained directly a transesterification and subsequent polycondensationnor the diaryl carbonate contained in the mixture after the reactionnseparated and with polyhydroaryl in a transesterification and polycondensationnis converted to polycarbonate. Furthermore, the invention relatesna process for producing diaryl carbonate by reacting boric triaryl estersnwith dialkyl carbonate. |
