PROBLEM TO BE SOLVED: To obtain a polycarbonate/graft polymer (specifically, an ABS-type) molding composition without generating a deposit during a thermoplastic treatment. SOLUTION: This thermoplastic polycarbonate/graft polymer molding composition consists of (A) 5-95 pts.wt. of an aromatic polycarbonate, (B) 1-50 pts.wt. of at least one sort of a thermoplastic homopolymer, a copolymer or a terpolymer from styrene, α-methyl styrene, acrylonitrile, an N-substituted maleimide or their mixture, (C) at least one sort of graft polymers of (C1) 5-90 pts.wt. styrene, α-methylstyrene, acrylonitrile, the N-substituted maleimide or their mixture on (C2) 95-10 pts.wt. of a rubber and (D) 1-25 pts.wt. of at least one additive selected from a flameproofing agent, a lubricant, an antistatic agent, a mold parting agent or their mixture.
