Polycarbonate transesterification with tetraborate or tetraaluminate anion containing catalyst |
| abstract |
An improved aromatic polycarbonate transesterification process comprising reacting a bis(aryl)carbonate and a phenol in the presence of a transesterification catalyst containing tetraborate or tetraaluminate anions, the improvement wherein the catalyst species is pre-formed under equilibration reaction conditions with either a phenol or a bis(aryl)carbonate prior to initiation of the transesterification reaction. |
