The present invention provides a thermoplastic resin composition, which is excellent in low-temperature toughness and high-temperature creep characteristics, by a method for producing a thermoplastic resin composition by melt-kneading:
(a) a polyphenylene sulfide resin, with
(b) a polyetherimide resin or a polyethersulfone resin, wherein the thermoplastic resin composition contains 99 to 1% by weight of the component (a) and 1 to 99% by weight of the component (b) based on 100% by weight of the total amount of the component (a) and the component (b); the melt-kneading step is the step of melt-kneading by an extruder provided with an elongational flow zone which is a zone in which melt-kneading is performed while being allowed to undergo elongational flow; and a flow effect pressure drop before and after the elongational flow zone is from 50 to 1,000 kg/cm 2 . |
