CONDUCTIVE RESIN COMPOSITION AND MOLDED OBJECT

摘要

A conductive resin composition characterized in that it comprises a polyamide (A), a polyphenylene ether (B) (terminal-unmodified polyphenylene ether and/or terminal-modified polyphenylene ether), a rubbery polymer (C), a conductive carbonaceous material (D) (carbon black and/or carbon fibrils), and a low-molecular modifier compound (E) (compatibilizing agent) and is produced by melt-kneading a mixture comprising the ingredients (A) to (E), and that the mixture has the following properties (1) to (3): (1) the amount of the ingredient (D) is 0.2 to 3 mass% based on the total amount of the ingredients (A) to (E); (2) the amount of the ingredient (E) is larger than 0.01 mass% and less than 0.20 mass% based on the total amount of the ingredients (A) to (E); and (3) the amount (a) of volatiles present in the ingredient (B) satisfies the relationship 0<=a<=-7.3xE+1.83 (E is the amount of the ingredient (E) (mass%)), provided that the amount (a) is the mass loss of the ingredient (B) (mass%) through 1-hour vacuum drying at 180°C.
