| titleOfInvention | Method for producing polycarbonate |
| abstract | (57) [Summary] [PROBLEMS] To improve the reaction rate and the like, and to produce a high-quality polycarbonate having a good color tone with little stagnant burning. To provide an efficient manufacturing method. SOLUTION: When producing a polycarbonate by polymerizing a polycarbonate prepolymer in a solid state or a swollen solid state, the polymerization is performed in a state where the oxygen concentration in the gas phase is 2 ppm or less and further the water concentration is 2 ppm or less. The production method of polycarbonate characterized by the following. |
