Novel multiblock poly(arylene ether sulfone)s were prepared by a two-pot method from a phenoxide-end-capped fully disulfonated poly(arylene ether sulfone) oligomer and a fluoride-end-capped nonsulfonated poly(arylene ether sulfone) oligomer with block length of 10 as the hydrophilic and hydrophobic

A series of cross-linkable sulfonated poly(arylene ether ketone)s bearing carboxylic acid groups (C-SPAEKs) have been prepared for direct methanol fuel cells (DMFCs). The chemical structure of the cross-linkable copolymers was analyzed by 1 H NMR and 13 C NMR spectra. Cross-linked membranes were obt
## Abstract This study describes the preparation and characterization of new ionomer blend membranes containing sulfonated poly(ether imide) (SPEI) and poly(ether sulfone) (PES). Thermogravimetric analysis indicated that the obtained blend membranes were more thermally stable than the parent SPEI.
