<p>Thermoplastic molding compositions which comprise (a) a poly(C2-6 alkylene terephthalate) resin and a minor proportion of (b) an aromatic polycarbonate resin which may also contain silicone units in combination with (c) a rubbery thermoplastic vinyl polymer which preferably contains olefinic units or a rubbery poly(carbonate-co-ester) resin, provide molded articles of improved impact resistance. Optionally the compositions contain a polyethylene resin as a processing and a fibrous reinforcing agent, a mineral filler, and a flame retardant. In preferred embodiments, articles molded from the compositions possess improved impact resistance, lower specific gravity, good tensile strength, improved resistance to distortion at elevated temperatures under load, and improved receptivity for colorants.</p> |
