| titleOfInvention | Method for producing high molecular weight aromatic polycarbonate resin |
| abstract | The present invention provides a method for producing a high-molecular-weight aromatic polycarbonate resin in which occurrence of a heterogeneous structure is suppressed and sufficient molecular weight can be achieved.nn n n A method for producing a high-molecular-weight aromatic polycarbonate resin, comprising the steps of: mixing a diol compound represented by the following general formula (1) with a catalyst to obtain a catalyst composition; and forming the obtained catalyst composition The step of transferring the material through the transfer tube to the prepolymer mixing tank at a transfer time of 10 hours or less; in the prepolymer mixing tank, the transferred catalyst composition is mixed with the aromatic polycarbonate prepolymer to obtain a prepolymer. A step of polymer mixture; and a step of quantifying the high molecular weight aromatic polycarbonate resin by heating the obtained prepolymer mixture under reduced pressure.nn n n n n n n n n n In the formula (1), R 1 to R 4 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 group selected from an aliphatic group, an aromatic group, an oxygen atom, A divalent group or a single bond which may have a substituent and is composed of at least one of the group consisting of a sulfur atom, a sulfo group, a fluorenylene group, a carbonyl group, a dialkylsilyl group, and a diarylsilyl group. |
