PURPOSE:To obtain the titled composition having high heat resistance, excellent mechanical properties, low mold shrinkage and high releasability, by compounding a fibrous reinforcing material or an inorganic filler in combination with a fluoroplastic to an aromatic polysulfone resin. CONSTITUTION:20-80(wt)% aromatic polysulfone resin is compounded with 10- 70% fibrous reinforcing material or inorganic filler and 0.5-20% fluoroplastic. The polysulfone is preferably a polymer having a reduced viscosity of 0.3-0.6 measured at 25 deg.C as a dimethylformamide solution containing 1g of the polymer in 100g of the solution. The fluoroplastic is preferably a tetrafluoroethylene resin (polytetrafluoroethylene). |
