Ion exchange properties polymer, ion exchange fiber and its production manner and ion exchange nonwoven fabrics

摘要

PURPOSE:To ensure flexibility and to facilitate fiber processing by introducing a functional ion exchange group into at least part of ethylene groups in the side chain of a polymer having syndiotactic poly(1,2-butadiene) structure as the structure of the principal chain. CONSTITUTION:A functional ion exchange group is introduced into at least part of ethylene groups in the side chain of a polymer having syndiotactic poly(1,2-butadiene) structure as the structure of the principal chain to synthesize an ion exchange polymer. The stock polymer preferably has at least units represented by formulae I, II, III (where at least one of X and Y is a group such as sulfonic acid, alkali metallic salt thereof, carboxyl or alkali metallic salt thereof). Jon exchange fibers are formed with the ion exchange polymer as at least part of starting materials.
