Title:
ION EXCHANGE MEMBRANE AND METHOD FOR PRODUCING ION EXCHANGE MEMBRANE WITH CATALYST LAYER
Document Type and Number:
WIPO Patent Application WO/2023/038133
Kind Code:
A1
Abstract:
The present invention provides: an ion exchange membrane which is not susceptible to swelling due to an aromatic compound even in a usage environment of an electrolytic hydrogenation apparatus; and a method for producing an ion exchange membrane with a catalyst layer. The present invention provides a method wherein a precursor resin is produced by polymerizing a monomer solution that has been filled into a base material, and a sulfonic acid type ion exchange group is subsequently introduced into the precursor resin. With respect to this method, the base material is a nonwoven fabric, a woven fabric or a porous membrane, each of which is configured from one or more resins that are selected from among polyolefins and fluororesins; and the monomer solution contains one or more monomers for ion exchange group introduction, the monomers being selected from among styrene, α-methyl styrene, vinyl naphthalene and vinyl toluene, and one or more crosslinkable monomers that are selected from among divinyl benzene and divinyl naphthalene.
