WARP-RESISTANCE REINFORCED THERMOPLASTIC COMPOSITIONS COMPRISING POLYESTER RESINS AND ZINC STEARATE

摘要

8CH-2323 Reinforced thermoplastic compositions provided comprising a poly(1,4-butylene terephthalate) resin, a resin selected from a poly (ethylene terephthalate) resin, a polycarbonate resin or a mixture thereof, a fibrous glass reinforcement and a minor amount of zinc stearate. The compositions are moldable to articles having improved resistance to warpage during heat treatment in comparison with molding compositions of glass reinforced poly(1,4butylene terephthalate).
