| titleOfInvention | Method for producing aromatic polycarbonate resin |
| abstract | An object of the present invention is to provide an improved production method capable of further reducing the amount of different structures in a method for producing an aromatic polycarbonate resin by a melt polymerization method. A method for producing an aromatic polycarbonate resin which obtains an aromatic polycarbonate resin having a high molecular weight from a polycarbonate prepolymer and a diol compound, wherein the polycarbonate prepolymer in a molten state contains a structural unit derived from an aromatic dihydroxy compound. Based on the first step of preparing the polymer, the second step of measuring the amount of blocked end groups of the polycarbonate prepolymer, and the measured amount of blocked end groups, the ratio of the diol compound to the polycarbonate prepolymer is determined. And a fourth step of reacting the polycarbonate prepolymer and the diol compound at a determined ratio to obtain a high molecular weight aromatic polycarbonate resin, wherein the fourth step is a polycarbonate. Start within 200 minutes of preparing the prepolymer That. [Selection figure] None |
