| titleOfInvention | Method for producing purified polycarbonate solution |
| abstract | (57) Abstract: It is an object of the present invention to provide a method for efficiently producing a purified polycarbonate solution having improved quality by effectively removing impurities contained in a polycarbonate solution, particularly supersaturated water. And SOLUTION: In a method for producing a purified polycarbonate solution by washing a crude polycarbonate solution after completion of a polycondensation reaction by an interfacial polycondensation method, stirring a crude polycarbonate solution after completion of a polycondensation reaction by an interfacial polycondensation method with washing water. After washing below, the crude polycarbonate solution containing the washing water is separated by static separation or centrifugation into an aqueous phase and an organic phase containing the polycarbonate, and then the organic phase containing the polycarbonate has a pore size of 20 to 18 A filtration filter of 0 μm is used, and a filtration flow rate is 60 to 1 A method for producing a purified polycarbonate solution, which comprises filtering under a condition of 000 mm / min. |
