PROBLEM TO BE SOLVED: To provide an antistatic resin composition affording a molded product having excellent antistatic properties, heat and chemical resistances and appearance of the molded product. SOLUTION: The antistatic resin composition is characterized as follows. The composition comprises (A) 7-91 mass% of an olefinic resin, (B) 3-30 mass% of a block copolymer containing an olefin polymer block (b1) and a hydrophilic polymer block (b2), (C) 1-50 mass% of a block copolymer containing a polymer block (c1) consisting essentially of an aromatic vinyl compound and a polymer block (c2) consisting essentially of a conjugated diene compound or a hydrogenated substance thereof and (D) 5-40 mass% of a styrenic resin. The component (A) is composed of an olefinic resin (A-1) without containing a cyclic olefin component and an olefinic resin (A-2) containing a cyclic olefin component and having 60-200°C glass transition temperature. The ratio ä(A-1)/(A-2)} of contents of both is (99/1) to (5/95) (mass ratio). COPYRIGHT: (C)2007,JPO&INPIT
