  • Patent number: 11511237
    Abstract: A polymerizable composition for forming an ion-exchange resin precursor, the polymerizable composition containing a monomer component and polyethylene particles in an amount of 50 to 120 parts by mass per 100 parts by mass of the monomer component, wherein the monomer component contains an aromatic monomer for introducing ion-exchange groups and a nitrogen-containing aliphatic monomer, the nitrogen-containing aliphatic monomer being present in an amount of 10 to 35% by mass in said monomer component. An ion-exchange membrane is produced by applying the polymerizable composition onto a polyolefin type filament base material and polymerizing the polymerizable composition to form an ion-exchange resin precursor and, thereafter, introducing ion-exchange groups into the precursor.
    Type: Grant
    Filed: March 9, 2021
    Date of Patent: November 29, 2022
    Assignee: ASTOM CORPORATION
    Inventors: Maki Kinoshita, Masayuki Kishino, Shunichiro Nakatsukasa, Kenji Fukuta
