PURPOSE:To obtain a resin composition having excellent characteristics and dimensional stability of a resin by blending a resin component containing an aromatic polycarbonate resin with an inorganic filler such as alumina, iron slag, metal powder or metal fiber and an organic acid. CONSTITUTION:A composition obtained by blending (A) 100 pts. wt. resin component containing an aromatic polycarbonate resin having 5000-50000, preferably 18000-30000 viscosity-average molecular weight or further <=70wt.% other thermoplastic resins added thereto with (D) >=1 pt.wt., preferably >=5 pts.wt. one or more inorganic fillers, selected from the group of alumina, iron slag, metal powder and metal fiber and having the surface optionally treated with a silane coupling agent, etc., and (C) an organic acid, preferably a <=15C aromatic carboxylic acid or <=20C aliphatic carboxylic acid (e.g. phthalic anhydride) in an amount of 0.1-10wt.%, preferably 1-10wt.% based on the component (B). |
