Patent ID: 8075805

Claim:
A method for producing a conductive resin composition comprising a polyamide resin, a polyphenylene ether and a carbonaceous filler comprising the steps of: (1) producing a conductive masterbatch in which 8 to 15% by weight of the carbonaceous filler is incorporated relative to the total weight of the conductive masterbatch, characterized by comprising a first step of melt-kneading a first polyamide and the carbonaceous filler to form a melt-kneaded product and a second step of melt-kneading the melt-kneaded product and a second polyamide, in this order, and (2) melting the polyphenylene ether; and adding the conductive masterbatch obtained in the step of (1) and the additional amount of polyamide simultaneously to the molten polyphenylene ether.
