ABSTRACT:
Ion exchange fibers comprising a polymer component having a main chain of a syndiotactic poly(1,2-butadiene) structure and containing ion exchange functional groups introduced at least part of side chain ethylene groups. These fibers may be suitably formed into a non-woven fabrics, and thus an ion exchange cloth can be obtained, which has excellent ion exchange capacity, flexibility excellent processing capacity, high mechanical strength and elongation. The ion exchange fibers have excellent ion exchange capacity with respect to fluid such as water or gas and thus can be used as cartridge filters and fiber-filled filters.
