PURPOSE:To provide the titled composition having excellent mechanical properties and thermal properties and improved stress cracking resistance, without lowering the other properties such as toughness, by compound potassium titanate fiber to the base resin. CONSTITUTION:95-99.5wt% an aromatic polysulfone having a reduced viscosity of 0.3-0.6 measured at 25 deg.C as a dimethylformamide solution containing 1g of the polymer per 100ml, is compounded with 5-0.5wt% of potassium titanate fiber having an average fiber length of 5-50mum, preferably 20-30mum and an average fiber diameter of 0.05-10mum, preferably 0.1-0.3mum.
