<P>PROBLEM TO BE SOLVED: To provide a branched aromatic polycarbonate composition which has improved flowability under a high load and a satisfactory hue and is hence suitable for use in processing by extrusion and injection molding, especially in applications such as: hollow parts formed by blow molding, which necessitates a material having high melt strength and giving an extrudate with excellent shape retention; large panels; and sheets formed by profile extrusion. <P>SOLUTION: The present invention relates to a method for producing the aromatic polycarbonate composition which includes a specific aromatic polycarbonate and a dye, wherein the dye comprises one or more compounds selected from Phthalocyanine Blue-based dyes and anthraquinone-based dyes, the content of the dye is from 0.01 ppm by weight to 100 ppm by weight, and the dye is added to the aromatic polycarbonate which is in a molten state immediately after polymerization. <P>COPYRIGHT: (C)2013,JPO&INPIT |
