| titleOfInvention | Branched polycarbonate manufacturing method |
| abstract | The method for producing a branched polycarbonate of the present invention comprises the following steps: (a), wherein a basic aqueous solution of a dihydric phenol, a carbon ruthenium chloride and a branching agent are subjected to a carbon chlorination reaction in the presence of an organic solvent to obtain a reaction liquid. And a step (b) of adding a basic aqueous solution of a dihydric phenol and a polymerization catalyst to the reaction liquid obtained in the step (a) to obtain a reaction liquid containing a polycarbonate oligomer; and the step (c); It separates the reaction liquid containing the polycarbonate oligomer obtained in the step (b) into an organic solvent phase and a water phase containing the polycarbonate oligomer; and the step (d), which is carried out in the step (c) The organic solvent phase containing the polycarbonate oligomer separated from the alkaline aqueous solution of the dihydric phenol is reacted to obtain a reaction liquid containing the branched polycarbonate; and the polymerization catalyst added in the step (b) is When the amount of addition is set to x mole/hr and the amount of the chloroformate group of the polycarbonate oligomer contained in the reaction liquid obtained in the step (b) is y mole/hr, (x /y) is set to 0.0035 or more. |
