Method for producing polycarbonate-polyorganosiloxane copolymer |
| abstract |
The present invention relates to a method for producing a polycarbonate-polyorganosiloxane catalyst, which comprises the step (a) of producing a polycarbonate oligomer using an alkaline aqueous solution of diphenol, phosgene and an organic solvent, and The content of the polycarbonate-polyorganosiloxane copolymer contained in the organic solvent introduced in the above step (a) is less than 850 ppm by mass. |
