titleOfInvention | Manufacturing method for high molecular weight aromatic polycarbonate resin |
abstract | Provided is a manufacturing method for a high molecular weight aromatic polycarbonate resin that has superior fluidity and for which a good color and a sufficiently high molecular weight can be achieved. A manufacturing method for a high molecular weight aromatic polycarbonate resin, said 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 kept in a molten state, and is mixed with an aromatic polycarbonate prepolymer within ten hours after obtaining the catalyst composition, 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. In formula (1), R 1 -R 4 each independently represent a hydrogen atom, a halogen atom, or a C1-5 straight-chain or branched-chain alkyl group. Q represents a single bond or a divalent radical that may contain a substituent group and is formed from at least one component selected from the group consisting of an aliphatic hydrocarbon group, an aromatic hydrocarbon group, an oxygen atom, a sulfur atom, a sulfone group, a sulfoxide group, a carbonyl group, a dialkylsilyl group, and a diarylsilyl group. |
