Document Type and Number:
WIPO Patent Application WO/2012/017965
Kind Code:
A1
Abstract:
Provided is an aromatic copolymer with sulfonic acid groups that has high proton conductivity, low swelling in hot water and low shrinkage during drying. The aromatic copolymer comprises polymer segments (A) containing structural units represented by formula (1) and polymer segments (B) containing structural units represented by formula (4).
(1) (4)
(In formula (1), each R1 independently represents a halogen atom, a C1-20 monovalent hydrocarbon group, or a C1-20 monovalent halogenated hydrocarbon group; a represents an integer of 0 to 3; and k represents an integer 1 to 4 with a+k being an integer of 4 or less. The multiple R1s can be the same or different.) (In formula (4), each E independently represents at least one structure selected from the group consisting of -CO-, -SO2-, -SO-, -CONH-, and -COO- groups; and Ar31, Ar32 and Ar33 each independently represent divalent or trivalent organic groups having benzene rings, naphthalene rings or nitrogen-containing heterocyclic rings or said organic groups wherein some or all of the hydrogen atoms have been substituted with fluorine atoms. R31 represents at least one structure selected from the group consisting of direct bonds, -O(CH2)p-, -O(CF2)p-, -(CH2)p-, and -(CF2)p- (p represents an integer of 1 to 12). e represents an integer of 0 to 10, f represents an integer of 1 to 5 and g represents an integer of 0 to 4.)
