Abstract: A polymerizable composition for forming an ion-exchange resin precursor, the polymerizable composition containing a monomer component and polyethylene particles in an amount of 50 to 120 parts by mass per 100 parts by mass of the monomer component, wherein the monomer component contains an aromatic monomer for introducing ion-exchange groups and a nitrogen-containing aliphatic monomer, the nitrogen-containing aliphatic monomer being present in an amount of 10 to 35% by mass in said monomer component. An ion-exchange membrane is produced by applying the polymerizable composition onto a polyolefin type filament base material and polymerizing the polymerizable composition to form an ion-exchange resin precursor and, thereafter, introducing ion-exchange groups into the precursor.

Abstract: An anion exchange membrane includes an anion exchange resin layer 3 reinforced with a backing material sheet 5. The anion exchange resin layer 3 includes an anion exchange resin that has as an anion exchange group a pyridinium group formed by protonation of a pyridyl group, and a vinyl chloride resin as a thickener. The backing material sheet 5 is made of a polyethylene woven fabric.
