<p><P>PROBLEM TO BE SOLVED: To provide an antistatic agent sustaining antistaticity over a long period, and not spoiling the appearance and transparency even if being kneaded in a resin, and to provide a resin composition containing the same. <P>SOLUTION: The antistatic agent is composed of a block copolymer obtained from an ester compound which is a reaction product of the following (a) and (b), or (a), (b) and (c), and is obtained by neutralizing a part or the whole of a residual acid group in the ester compound with an alkaline substance. The thermoplastic resin composition contains the antistatic agent. A film and a sheet are composed of the thermoplastic resin composition. (a) A polyolefin whose one terminal is modified with an acid. (b) A compound having a polyoxyalkyelene group and a hydroxide group and/or an amino group. (c) A compound reactive with (a) and/or (b). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
