titleOfInvention | Method for producing polycarbonate-polyorganosiloxane copolymer |
abstract | A method for producing a polycarbonate-polyorganosiloxane copolymer having excellent transparency is provided. A method for producing a polycarbonate-polyorganosiloxane copolymer by introducing a polycarbonate oligomer, an alkaline aqueous solution of a dihydric phenol and a polyorganosiloxane into a polycondensation reaction zone and subjecting the polycondensation reaction zone to a polycondensation reaction. In addition, before introducing into the polycondensation reaction zone, an organic solvent is supplied to the polyorganosiloxane to prepare a polyorganosiloxane solution, and the supply of the organic solvent in the step (1) is performed. A process for producing a polycarbonate-polyorganosiloxane copolymer, which is carried out in a plurality of stages and reduces the polyorganosiloxane solution concentration stepwise.
