PURPOSE:To obtain the titled composition of improved solvent resistance without impairing high high-temperature rigidity and high-temperature creep resistance, etc., by incorporating specified amount of specific filler in a resin composition comprising polyether ketone and aromatic polysulfone. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts. by wt. of a composition comprising A1: 20-95wt% of a polyether ketone having recurring unit of formula I (X1, X2 and X3 are each of formulae II, III, etc.; Q is -0-, etc.; K is 0-3) with a melt viscosity y at 400 deg.C satisfying the equation: 100<=y<=70x+1,000 (x is wt% of the polyether ketone to the sum of the polyether ketone and aromatic polysulfone) and A2: 80-5wt% of an aromatic polysulfone having recurring unit of formula IV (divalent aromatic residue) with (B) 10-200 (pref. 15-200)pts. by wt. of filler with an average fiber length or diameter >=5mum (e.g., glass fiber).
