Manufacturing method for high molecular weight aromatic polycarbonate resin |
| abstract |
Provided is a high molecular weight aromatic polycarbonate resin manufacturing method that suppresses the occurrence of heterogeneous structures and can achieve a sufficiently high molecular weight. A high molecular weight aromatic polycarbonate resin manufacturing method including: a step in which a dialcohol compound expressed by general formula (1) and a catalyst are mixed to obtain a catalyst composition; a step in which the obtained catalyst composition is transferred to a prepolymer mixing tank via a transfer pipe, with a transfer period of 10 hours or less; a step in which the transferred catalyst composition and an aromatic polycarbonate prepolymer are mixed in the prepolymer mixing tank to obtain a prepolymer mixture; and a high molecular weight achievement step in which the obtained prepolymer mixture is heat-treated under reduced pressure conditions to obtain a high molecular weight aromatic polycarbonate resin. |
