Title:
SULFONATED POLYMER AND SOLID POLYELECTROLYTE
Document Type and Number:
Japanese Patent JP2006028415
Kind Code:
A
Abstract:

To provide a sulfonated polymer that can retain excellent resistance to hot water even when the introduction of sulfonic acid groups is increased, to provide a solid polyelectrolyte that is composed of the sulfonated polymer, has high proton conductivity and shows excellent mechanical properties and high electrogenicity, further provide a proton conductive film.

This polyarylene polymer has a constitution unit that is led from a compound having a specific structure, preferably includes a constitution unit represented by general formula (1') [wherein A is a divalent electron-attractive group or sulfur or a direct bond; B is oxygen or sulfur atom; R1 to R12 are each H, F or an alkyl; m is an intger of 1 or more and n is an integer of 2 or more; Q has a structure, for example, represented by general formula (2) (wherein D is a divalent atom or organic group or a direct bond, R9 to R16 are each H, F, an alkyl or an aromatic group)].
