    • PROBLEM TO BE SOLVED: To obtain a resin composition which can give a molding improved in high-temperature strengths, impact resistance, and flame retardancy by incorporating a polyetherimide resin with an aromatic polycarbonate resin and a functionalized polysiloxane polymer. SOLUTION: This composition is prepared by adding 0.1-4.0 pts.wt. functionalized polysiloxane polymer represented by formula IV (wherein R1 to R10 are each a 1-20C alkyl, a 2-26C alkenyl, a 2-20C alkynyl, or the like) and having a weight-average molecular weight of 1,500-30,000 g/mol to 100 pts.wt., in total, 60-90 pts.wt. polyetherimide resin having 1,000 or more structural units each represented by formula I (wherein the divalent group T is one which bridges the positions 3, 3', 3, 4', 4, 3', or 4, 4' of the aryl ring of an arylimide moiety; T is -O- or -O-Z-O; Z is a divalent group selected from formula II, etc.; X is a divalent group of formula III or the like; y is 1-5; and R is a divalent organic group such as a 6-20C aromatic hydrocarbon group) and 10-40 pts.wt. aromatic polycarbonate resin having an intrinsic viscosity of 0.3-1.5 dl/g (in methylene chloride at 25 deg.C) and a weight-average molecular weight of 30,000 g/mol or above.
