Abstract

See full text

Provided is a functional polymer membrane having a structure represented by the following Formula (1) and a structure represented by the following Formula (2), in which an ion exchange capacity is 2.0 meq/g to 7.0 meq/g; and a method for producing the same,

description='In-line Formulae' end='lead'—S-LL1-LL-LL2-S—   Formula (1)description='In-line Formulae' end='tail'

    in Formula (1), LL represents a single bond or an alkylene group which may have a substituent, —O—, —S—, —NRZ— or a linking group obtained by combining these, LL1 and LL2 represent —(CR1R2)I— or —(CR1R2)I—C(═O)O— (in which the atom bonded to LL is an oxygen atom), R1 and R2 represent a hydrogen atom or an alkyl group, I represents 1 or 2, RZ represents a hydrogen atom or a substituent, however, in a case where terminal atoms of a substituent in LL and a substituent of RZ are a sulfur atom, LL is the sulfur atom having a bond to be incorporated into the polymer chain, and
