СПОСОБ ПОЛУЧЕНИЯ СМОЛЫ С ВЫСОКОЙ СТЕПЕНЬЮ ПОЛИМЕРИЗАЦИИ НА ОСНОВЕ АРОМАТИЧЕСКОГО ПОЛИКАРБОНАТА |
摘要 |
The present invention is to provide a process for preparing a highly polymerized aromatic polycarbonate resin, which comprises the steps of a highly polymerizing step for reacting an aromatic polycarbonate prepolymer and an aliphatic diol compound in the presence of a transesterification catalyst to obtain a highly polymerized aromatic polycarbonate resin, a cyclic carbonate removal step for removing at least part of the cyclic carbonate by-produced in the above highly polymerizing step out of the reaction system, and a recycle step of hydrolyzing the cyclic carbonate removed in the cyclic carbonate removal step to obtain an aliphatic diol compound and using the obtained aliphatic diol compound as at least a part of the aliphatic diol compound to be used in the highly polymerizing step. |
