Abstract: A series of sulfonated poly(phthalazinone ether ketone) ionomers containing poly(fluorene ether ketone) hydrophobic moieties as the polymer electrolytes for fuel cell appliaction were synthesized. To obtain multiblock poly(phthalazinone ether ketone) ionomers, one-pot two step nucleophilic polycondensation was run. Ionomers with various IEC were synthesized by adjusting the molar ratios and feeding sequence of fluorene bisphenol, bisphthalazinone monomer, sulfonated difluoro benzophenone, and difluoro benzophenone. The so-made polymers have high molecular mass, good thermal stabilities, oxidation resistance and hydrolysis resistance, moderate water-uptakes. They demonstrate good alcohol resistance at refluxing temperature and proton conductivity and can be potentially used as proton exchange membranes for fuel cells.

Key words: Fluorene bisphenol, Poly(phthalazinone ether ketone), Sulfonation, Polycondensation, Ionomer
