    Abstract: Provided are: an antistatic agent which is capable of imparting excellent antistatic effect in a small amount and has sufficient persistence and wiping resistance; an antistatic agent composition; an antistatic resin composition; and a molded article. The antistatic agent comprises a polymer compound (E) having a structure in which a block polymer (C) and an epoxy compound (D) are bound via an ester bond formed by a carboxyl group of the block polymer (C) and an epoxy group of the epoxy compound (D), the block polymer (C) having a structure comprising carboxyl groups at both ends, in which structure a block constituted by a polyester (A) having carboxyl groups at both ends and a block constituted by a compound (B) having hydroxyl groups at both ends are repeatedly and alternately bound via ester bonds formed by the carboxyl groups and the hydroxyl groups, and the epoxy compound (D) comprising two or more epoxy groups.

    Abstract: Provided: polyolefin resin composition excellent in antistatic properties with sufficient persistence and wiping resistance, without impairment of intrinsic mechanical properties; and an automotive interior/exterior material containing the same. The polyolefin resin composition contains: 50 to 90 parts by mass of polyolefin resin; 3 to 40 parts by mass of thermoplastic elastomer; 3 to 30 parts by mass of filler, and an antistatic agent of a polymer compound (E) in an amount of 3 to 20 parts by mass with respect to a total amount of 100 parts by mass of the polyolefin resin, thermoplastic elastomer and filler, wherein the polymer compound (E) has a structure in which a diol, an aliphatic dicarboxylic acid, an aromatic dicarboxylic acid, a compound (B) containing at least one group of Formula (1) and having hydroxyl groups at both ends, and an epoxy compound (D) having two or more epoxy groups are bound via ester bonds: —CH2—CH2—O—  (1).
