(57) [Summary] [Structure] A polymer having the formula (I): (In the above formula, n is 0 or a number of 1 or 2; R 1 is H or methyl; M + is H + , an alkali metal cation or an ammonium cation; X is C 1 -C 4 alkyl, C 1 -C 4 alkoxy, Cl or B r; and Z is a group of an olefin monomer other than formula (I)), which is 5 to 100 mol% of the same or different structural units and 0 to 9 of the same or different structural units of the formula (II). A polymer comprising 5 mol%, a method for producing the same, and a composition containing the polymer. [Effects] Molded articles and films containing the above composition have high electrical conductivity, and include, for example, conductors, electrodes, battery cathodes It can be used as an electromagnetic shielding material, a sensor, an antistatic filling material or a conductive encapsulating material. |
