Claim 4:
5. A conductive polyamide resin composition, comprising:
5% to 20% by weight of the conductive concentrated resin composition according to claim 1;
35% to 65% by weight of a second polyamide resin, wherein the first and second polyamide resins are the same;
0% to 40% by weight of a poly(arylene oxide) resin, wherein the poly(arylene oxide) resin comprises one or more selected from the group consisting of poly(2,6-dimethyl-1,4-phenylene)ether, poly(2,6-diethyl-1,4-phenylene)ether, poly(2,6-dipropyl-1,4-phenylene)ether, poly(2-methyl-6-ethyl-1,4-phenylene)ether, poly(2-methyl-6-propyl-1,4-phenylene)ether, poly(2-ethyl-6-propyl-1,4-phenylene)ether, poly(2,6-diphenyl-1,4-phenylene)ether, poly(2,3,6-trimethyl-1,4-phenylene)ether, poly(2,3,6-triethyl-1,4-phenylene)ether, modified polymers thereof, and copolymers thereof;
1% to 15% by weight of a second polar polymer, wherein the first and second polar polymers are the same;
1% to 20% by weight of a second non-polar polymer, wherein the first and second non-polar polymers are the same;
0% to 15% by weight of a third polar polymer or a third non-polar polymer as an impact modifier, wherein the third polar polymer or the third non-polar polymer comprises an aromatic vinyl elastomer; and
0% to 35% by weight of an inorganic filler, wherein the inorganic filler comprises one or more selected from the group consisting of glass fiber, talc, mica, wollastonite, barium sulfate, barium carbonate, and silica,
based on a total weight of the conductive polyamide resin composition,
wherein the modified polymer of the poly(arylene oxide) resin is a reaction produce of the poly(arylene oxide) resin with one or more reactive monomers selected from the group consisting of citric acid, maleic acid, itaconic acid, fumaric acid, (meth)acrylic acid, anhydrides thereof, and (meth)acrylic acid esters.
