A thermoplastic composition comprising a resinous blend of (A) aromatic polycarbonate and (B) polyester, (C) nanoclay and (D) carboxylic acid is disclosed. The composition features improved melt stability and impact strength over corresponding compositions that contain no acid. The nanoclay is present in an amount of 0.1 to 30 percent relative to the weight of the resinous blend, and the acid is present in an amount of 1 to 20 percent relative to the weight of the nanoclay. The average thickness of the clay particles is about 1 to 100 nm, and their average lengths and average widths, independently one of the other are 50 to 700 nm.
