The present invention provides a method for producing a high molecular weight aromatic polycarbonate resin, which comprises the steps of: mixing a diol compound represented by the following general formula (1) with a first catalyst to obtain a catalyst composition, Mixing the catalyst composition with the aromatic polycarbonate prepolymer to obtain a prepolymer mixture, and heat-treating the prepolymer mixture under reduced pressure to obtain a high molecular weight aromatic polycarbonate step.n□ In the general formula (1), R1 to R4 each independently represent a hydrogen atom, an alkyl group or the like. Q represents a divalent group or a single bond. |
