<P>PROBLEM TO BE SOLVED: To obtain a polycarbonate resin composition containing an aromatic polycarbonate resin, an aromatic polyester resin and a basic inorganic filler, and having a good heat stability. <P>SOLUTION: The polycarbonate resin composition consists of (component (a)) the aromatic polycarbonate resin, (component (b)) the aromatic polyester resin, (component (c)) the basic inorganic filler and (component (d)) a phosphite stabilizer, (i) contains 0.005-5 pts. wt. (d) component based on 100 pts. wt. total of the (a), (b) and (c) components, also has a ratio of (the component (a))/(the component (b))=5-95 wt. %/5-95 wt. %, and (ii) has an acid value of the component (d) within 0.1-30 mgKOH/g range acid value elevation under a specific condition. The method for producing the polycarbonate resin composition is provided by using an extruder having at least 2 positions of supplying ports and at least supplying the components (a) and (d) from a first supplying port, and the components (b) and (c) from a second supplying port or ports after that. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
