ABSTRACT:
PROBLEM TO BE SOLVED: To provide a production method for a thermoplastic resin composition, composed of a polyphenylene ether and a polyamide, having an electric conductivity, and excellent in balance of fluidity and impact strength, by producing with a specific process, and to provide the thermoplastic resin composition obtained thereby.SOLUTION: The thermoplastic resin composition is composed of the following component (A)-(E), wherein a weight ratio of (A)/(B) is 5/95-70/30, an amount of (C) is effective to phase-solvate (A) and (B), the amount of (D) is 0.8-10 pts.wt. per the total 100 pts.wt. of (A) and (B), and the amount of component (E) is 5-40 pts.wt. per the total 100 pts.wt. of (A) and (B). The production method for the thermoplastic resin composition is provided. (A): a polyphenylene ether, (B): a polyamide. (C): a phase-solvating agent, (D): an electrically conductive carbon black and/or a fine fibrous carbon, and (E) an improving agent for shock resistance.
