Abstract:
Provided is an ion-exchange fiber including a polymer A obtained by introducing an ion-exchangeable substituent to 100 parts by weight of an acrylic polymer that is obtained by polymerization of a monomer composition containing 30 % by weight or more of acrylonitrile with respect to 100 % by weight of the composition and a polymer B obtained by introducing an ion-exchangeable substituent to 1 part by weight or more and 100 parts by weight or less of an epoxy group-containing polymer. Each ion-exchangeable substituent is introduced by reaction with an amine compound and is an ion-exchangeable substituent derived from the amine compound. A method for producing the ion-exchange fiber is also provided.
