8CH 2325 ABSTRACT OF THE DISCLOSURE Reinforced thermoplastic compositions are provided comprising a poly(1,4-butylene terephthalate) resin, a poly(ethylene terephthalate) resin, and a reinforcing, warp resisting combination of talc and silica. The compositions optionally include a segmented copolyester resin, a silicone polymer and/or a fibrous glass reinforcement. The compositions are moldable to articles having improved resistance to warpage during heat treatment in comparison with molding compositions of talc, (poly(1,4-butylene terephthalate) and poly (ethylene terephthalate).
