REINFORCED THERMOPLASTIC COMPOSITIONS OF POLYESTER RESINS AND GLASS FIBERS IN COMBINATION WITH FINE GROUND MICA

摘要

8 CH 2327 Reinforced thermoplastic compositions are provided comprising a poly(1,4-butylene terephthalate) resin, a poly(ethylene terephthalate) resin, and a reinforcement comprising fibrous glass combined with finely ground mica. The compositions are moldable to articles having improved resistance to heat distortion or warpage in comparison with molding compositions of glass reinforced polyblends of poly(1,4-butylene terephthalate) and poly(ethylene terephthlate).
