METHOD FOR PRODUCTION OF AROMATIC POLYCARBONATE RESIN COMPOSITION

摘要

Disclosed is a method for producing an aromatic polycarbonate resin composition having stabilized quality by mixing an aromatic polycarbonate resin with an additive such as a thermal stabilizer homogeneously. Specifically disclosed is a method for producing an aromatic polycarbonate resin composition, which comprises the following steps: a polycarbonate feed step for feeding an aromatic polycarbonate in a molten state to an extruder continuously; an extrusion step for mixing the aromatic polycarbonate with a thermal stabilizer in the extruder and extruding the mixture from the extruder; a pellet formation step for pelletizing the aromatic polycarbonate extruded from the extruder to form a pellet of the aromatic polycarbonate; and a pellet circulation/feed step for collecting a part of the aromatic polycarbonate pellets, and continuously feeding the pellet impregnated with the thermal stabilizer to the extruder into which the aromatic polycarbonate is to be fed in the polycarbonate feed step, while impregnating the pellet with the thermal stabilizer continuously.
