Provided is an ion exchange film including a resin which is disposed in pores of a porous support and made of a styrene-acryl copolymer having a structure expressed by General Formula (PI) or (PII) below, a composition for forming the film, and a production method therefor.
R 1 and R 2 represent a hydrogen atom or an alkyl group, Y 1 and Y 2 represent -O- or -N(Rx)-, and Rx represents a hydrogen atom or an alkyl group. L 1 represents a p1 + 1-valent linking group having 2 or more carbon atoms, L 2 represents a bivalent linking group, p1 represents an integer of 1 or greater, and n1, n2, and m1 represent integers of 1 or greater. R a to R g represent alkyl groups or aryl groups, 2 or 3 of R a to R c may be bonded to each other to form a ring, and 2 to 4 of R d to R g are bonded to each other to form a ring. X 1 - to X 4 - represent an organic or inorganic anion. |
