Electrically Conductive Resin Composition Of A Polyamide Type, Process For The Production Thereof, And Cap For Fuel Tank Comprising It

Abstract

An electrically conductive resin composition of a polyamide type, characterized in that, (A) 95 to 40% by mass of polyamide resin, (B) 5 to 30% by mass of electrically conductive carbon black, (C) 10 to 40% by mass of an ethylene-α-olefin copolymer having a reactive functional group which is able to react with a terminal group of the polyamide resin and/or an amide group of the main chain and (D) 1 to 10% by mass of a high-density polyethylene resin are compounded; the polyamide resin (A) forms a continuous phase; the ethylene-α-olefin copolymer (C) in particles having an average particle diameter of not more than 2 μm is present by being dispersed in the continuous phase of the polyamide resin (A); and not less than 80% by mass of the electrically conductive carbon black (B) is present by being dispersed in the polyamide resin phase (A) which is a continuous phase, as well as a cap for fuel tank comprising it.
