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

## Abstract With a view towards direct methanol fuel cell applications, novel sulfonated poly(phenylene sulfide sulfone nitrile) (sPPSSfN) has been prepared and subsequently crosslinked by a FriedelβCraft reaction using 4,4β²βoxybis(benzoic acid) as a crosslinker to achieve lower water swelling and
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
