Title:
ポリアゾールをベースとするポリマーフィルム、およびその使用
Document Type and Number:
Japanese Patent JP2005537380
Kind Code:
A
Abstract:
Production of proton-conducting polymer membranes comprises (a) producing a mixture of polyphosphoric acid, polyazole(s) and/or compound(s) forming polyazoles on heating in step (b), (b) heating the mixture under inert gas up to 400 degrees C; (c) applying a layer of the mixture from (a) and/or (b) to a substrate; and (d) treating the resultant membrane, the novelty is that (d) uses a hydrolysis liquid comprising phosphorus and/or sulfur oxyacid(s). Independent claims are also included for the following: (1) proton-conducting polymer membrane produced by this process, which has a phosphoric acid concentration not less than 85 wt.% at a breaking stress of not less than 30 kJ/m2; (2) proton-conducting polymer membrane comprising phosphoric acid, polyazole(s) and monomer(s) (I) capable of free radical polymerization and having phosphonic and/or sulfonic acid groups, in which the weight ratio of the sum of phosphoric acid, polyphosphoric acid and polyphosphoric acid hydrolysis products to (I) is at least 1:2.
