Title:
POLYMER ELECTROLYTE MEMBRANE COMPOSED OF AROMATIC POLYMER MEMBRANE BASE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/023801
Kind Code:
A1
Abstract:
Disclosed is a polymer electrolyte membrane which is characterized by being produced by a process wherein a vinyl monomer is introduced as a graft chain into an aromatic polymer membrane base, which is typified by a polyether ether ketone, polyether imide or polysulfone, by graft polymerization and then a part of the graft chain or/and the aromatic polymer chain is chemically converted into a sulfonic acid group. Also disclosed is a method for producing such a polymer electrolyte membrane.
