Polymer electrolyte membranes comprising alkyl graft chains and a process for producing the same |
摘要 |
Polymer electrolyte membranes for use in fuel cells are produced by first graft polymerizing acrylic acid derivatives or vinylketone derivatives as monomers on polymer substrates and by then performing selective conversion to a sulfonic acid group of hydrogen atoms on the carbon atom adjacent to the carbonyl in the ketone or carboxyl group on the graft chains. |
