Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for a thermoplastic resin composition which is excellent in heat resistance and impact resistance, and also, exhibits special viscoelastic characteristics when the thermoplastic resin composition is formed into a molded article, fiber or film. SOLUTION: This manufacturing method is used for a thermoplastic resin composition (I) comprising a thermoplastic resin (A) and a resin (B) having a reactive functional group, or for a thermoplastic resin composition (II) comprising a thermoplastic resin (A), a thermoplastic resin (C) being different from the thermoplastic resin (A) and a compound (D) having a reactive functional group. In the manufacturing method for the thermoplastic resin composition, material resins are molten and kneaded under a condition in which a dwell time from the feeding of the material resins into a biaxial extruder to the extrusion thereof is 1 to 30 minutes, and the extrusion amount is 0.01 kg/h per 1 rpm of a screw rotation or more by using a biaxial extruder having a ratio L/D 0 of the screw length L and the screw diameter D 0 of 50 or more.
