Document Type and Number:
WIPO Patent Application WO/2024/096603
Kind Code:
A1
Abstract:
The present invention pertains to a method for producing an anionic fluorine polymer containing a perfluoro sulfonic acid group, the method comprising: polymerizing a first monomer, containing a perfluoro sulfonic acid group represented by chemical formula 1, and a second monomer, which is at least one selected from the group consisting of vinylidene fluoride, tetrafluoroethylene, and chlorotrifluoroethylene. CF2=CF-O-[CF2-CF(CF3)-O]m-[CF2]n-SO2F, where m is an integer of 0-3, and n is an integer of 2-4.
