PROBLEM TO BE SOLVED: To provide a continuous manufacturing method for a polycarbonate composition capable of stably manufacturing the polycarbonate composition reducing the lowering of a molecular weight at the time of production of the composition, excellent in heat stability such as hue holding properties or the like and sufficiently developing the function of a kneading component such as an additive or the like. SOLUTION: A polycarbonate resin is supplied from the first supply port of a kneader having a plurality of supply parts, and an additive is supplied from a second supply port on the downstream side of the first supply port to be kneaded with the polycarbonate resin or the polycarbonate composition to manufacture the polycarbonate composition. The kneading component is added to the polycarbonate resin held to a molten state in the kneader using a cooled feeder before kneaded with the polycarbonate resin. COPYRIGHT: (C)2004,JPO |
