Abstract
Improved polyester compositions exhibiting improved gloss and resistance to warping comprise crystallizable polyester resins, e.g., poly(ethylene terephthalate) optionally with poly(1,4-butylene terephthalate) and a reinforcing agent, the improvement comprising adding a modifier selected from an amorphous or semi-crystalline thermoplastic for gloss and warp resistance improvement. The molding compositions exhibit excellent resistance to warp even after adding significant amounts of reinforcing glass filaments.
