ABSTRACT:
An antistatic resin composition comprises 100 parts of a nitrile copolymer comprising 7 to 100% of a nitrile graft copolymer with a graft ratio of 4 to 50% obtained by graft-polymerizing a monomer mixture of a specific composition onto a rubber trunk polymer predominantly comprising a conjugated diolefin and/or an acrylate, and 0 to 93% of a nitrile random copolymer of a specific composition; and 0.05 to 10 parts of a surfactant added thereto. This antistatic resin composition, wherein the rubber trunk polymer forms a bridge structure, not only has, per se, an excellent antistatic property but also an antistatic property which undergoes substantially no change upon washing, for example, with water.
