Abstract
A perfluoropolyether rubber composition is useful for forming a polymer electrolyte membrane, comprising (A) an alkenyl-containing perfluoropolyether, (B) a silicon-oxygen crosslinked structure having ionic conduction, and (C) a peroxide crosslinker. The silicon-oxygen crosslinked structure is obtained by simultaneously effecting oxidation and hydrolysis on an organoxysilane having an epoxy group and an organoxysilane having a mercapto group for thereby converting the mercapto group into a sulfonic group, and neutralizing the resulting sulfonic group-containing siloxane with a nitrogen-containing compound.
