Title:
POLYMER, METHOD FOR PRODUCING POLYMER AND METHOD FOR PRODUCING FILM
Document Type and Number:
WIPO Patent Application WO/2020/129991
Kind Code:
A1
Abstract:
The present invention provides a polymer wherein a linking group that connects a cyclic perfluoroaliphatic disulfonimide skeleton and the main chain of the polymer is a fluoroalkylene group that may have an ether oxygen atom. A polymer which has one or both of a unit represented by formula u1-1 and a unit represented by formula u1-2. In the formulae, each of RF1 and RF
2 represents a perfluoroalkylene group having 1-3 carbon atoms; RF3 represents a perfluoroalkylene group having 1-6 carbon atoms; m represents 0 or 1; and X represents a hydrogen atom, an alkali metal atom, a fluorine atom, an alkyl group, an ammonium or the like.
