<p>Modified thermoplastic polyester compositions which comprise (a) a poly(1,4-butylene terephthalate) resin in combination with a poly(ethylene terephthalate) resin and /or a polyester copolymer and (b) a modifier therefor comprising a combination of a selectively hydrogenated monoalkenyl arene-diene block copolymer resin and an aromatic polycarbonate. The compositions can include (c) reinforcing glass fibers and/or (d) a flame retardant. Modifier (b) provides enhanced resistance to impact fracture, increased strength and improved resistance to heat distortion in articles molded from the compositions. </p> |
