PROCESS FOR PRODUCING A HIGH MOLECULAR-WEIGHT AROMATIC POLYCARBONATE RESIN

摘要

The present invention is to provide a process for producing a high molecular-weight aromatic polycarbonate resin, the process includes mixing a dialcohol compound represented by the following Formula (1) with a first catalyst to obtain a catalyst composition; mixing the obtained catalyst composition with an aromatic polycarbonate prepolymer to obtain a prepolymer mixture; and obtaining a high molecular-weight aromatic polycarbonate by subjecting the obtained prepolymer mixture to heating treatment under reduced pressure condition. In the Formula (1), R1 to R4 each independently represent a hydrogen atom, an alkyl group and the like. Q represents a divalent group or a single bond.;

1. A process for producing a high molecular-weight aromatic polycarbonate resin, the process comprising:
mixing a dialcohol compound represented by the following Formula (1) with a first catalyst to obtain a catalyst composition; mixing the obtained catalyst composition with an aromatic polycarbonate prepolymer to obtain a prepolymer mixture; and obtaining a high molecular-weight aromatic polycarbonate by subjecting the obtained prepolymer mixture to heating treatment under reduced pressure conditions: wherein, in Formula (1), R1 to R4 each independently represent a hydrogen atom, a halogen atom, or a linear or branched alkyl group having 1 to 5 carbon atoms; and Q represents a divalent group comprising at least one member selected from the group consisting of an aliphatic hydrocarbon group, an aromatic hydrocarbon group, an oxygen atom, a sulfur atom, a sulfonic group, a sulfoxide group, a carbonyl group, a dialkylsilyl group, and a diarylsilyl group and optionally having a substituent, or a single bond.
