Method for producing polycarbonate-polyorganosiloxane copolymer |
| abstract |
Disclosed is a method for efficiently producing a polycarbonate-polyorganosiloxane copolymer by avoiding poor separation between an organic phase and an aqueous phase in a treatment step after polycondensation. A polycarbonate-polyorganosiloxane copolymer is produced by introducing a polycarbonate oligomer, an alkaline aqueous solution of dihydric phenol, polyorganosiloxane, and triethylamine into a polycondensation reaction zone and subjecting the polycondensation reaction zone to a polycondensation reaction. In the method, a polycarbonate-polyorganosiloxane copolymer is produced by mixing triethylamine with an organic solvent in a pipe before introducing it into the polycondensation reaction zone.
