| titleOfInvention | Method for producing polycarbonate resin |
| abstract | An object of the present invention is to reduce the amount of phenol contained in a polycarbonate resin composition to be obtained and to suppress a bad odor. A molten polycarbonate resin obtained by polycondensation reaction of a dihydroxy compound and diphenyl carbonate is supplied to a kneading extruder equipped with a vent part, a water injection part and a screw, and subjected to water injection devolatilization treatment. It is a manufacturing method, Comprising: The vent-port area (A) of this vent part per said molten polycarbonate resin flow volume shall be the conditions of following formula (1), The molten polycarbonate resin temperature at the outlet of the kneading extruder is 350 ° C. or less, and the screw rotation speed (n) is a condition of the following formula (2). A ≧ 1.5 × 10 −4 (m 2 / (kg / h)) (1) n 3 × d 2 > 25000 (2) (In the formula (2), n represents the screw rotation speed (rpm) and d represents the screw diameter (m).) [Selection figure] None |
