Title:
SULFONIC ACID GROUP-CONTAINING POLYMER, METHOD FOR PRODUCING THE SAME, POLYMER ELECTROLYTE MEMBRANE USING SULFONIC ACID GROUP-CONTAINING POLYMER, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2008/038702
Kind Code:
A1
Abstract:
Disclosed is a novel sulfonic acid group-containing polymer which is excellent in flexibility and stability, and suitably used in fuel cells and the like. Specifically disclosed is a sulfonic acid group-containing polymer characterized by having at least structural units represented by the chemical formulae 1 and 2 below. [In the chemical formulae 1 and 2, X represents an -S(=O)2- group or a -C(=O)- group; Y represents H or a monovalent cation; R1 represents an alkylene group having 1-10 carbon atoms, an arylene group or a direct bond; R2 represents an alkylene group having 2-20 carbon atoms or an aralkylene group; Ar1 represents a divalent aromatic group having an electron-withdrawing group; and n and m represent the mole number of the respective structural units.]
