Abstract: A method of the present invention for producing an anion exchange membrane includes the steps of: (i) irradiating a first polymer film with radiation; and (ii) graft-polymerizing a monomer containing a site into which a functional group having anion conducting ability can be introduced and an unsaturated carbon-carbon bond onto the radiation-irradiated first polymer film so as to form a second polymer film containing grafted chains. This method further includes the subsequent steps of: (a) subjecting the second polymer film to a treatment including irradiation with radiation so as to introduce a crosslinked structure into the grafted chains; and (b) introducing the functional group having anion conducting ability into the site.

Abstract: Disclosed is a production method including the steps of: graft-polymerizing a first monomer onto a polymer substrate so as to form a first graft polymer; and graft-polymerizing a second monomer onto the first graft polymer so as to form a second graft polymer. The first monomer contains a polar group. The second monomer contains at least one selected from the group consisting of an ion-conducting group and a site into which an ion-conducting group can be introduced. The second monomer has a higher polarity than the first monomer.
