PURPOSE: To obtain a thermoplastic resin composition, comprising an aromatic polysulfone resin, a polyamide resin and an amino group-containing aromatic polysulfone resin and excellent in balance among physical properties such as heat and chemical resistances and moldability.
CONSTITUTION: This thermoplastic resin composition comprises (A) 5-95wt.% aromatic polysulfone resin, (B) 95-5wt.% polyamide resin (e.g. nylon 6) and (C) an aromatic polysulfone resin having amino groups in an amount of ≥20×10-6 equiv. based on 1g resin in an amount of 1-95wt.% based on the total amount of the resin composition. Furthermore, the component (A) is preferably a resin at (10-60):(40-90) mol% ratio of a unit, produced by condensing hydroquinone with a dihalogenosulfone compound and expressed by formula I to a unit, produced by condensing 4,4'-biphenol with the dihalogenosulfone compound and expressed by formula II. The component (C) is prepared by using, e.g. a dihydric phenol compound and a bivalent aminophenol compound in combination. p-Aminophenol is preferred as the bivalent aminophenol compound.
