  A fluorine-containing polyether compound represented by the following general formula : is prepared by reaction of a fluorine-containing dicarboxylic acid fluoride having the following general formula :         FOCCF(CF3)[OCF2CF(CF3)]1OCF2CF2O[CF(CF3)CF2O]mCF(CF3)COF (l+m:30-130) with an aromatic amine represented by the following general formula : XC6H4NHR1(R1:H, alkyl group or phenyl group ; X:I or Br). A curable fluorine-containing polyether composition is formed by compounding the resulting fluorine-containing polyether compound with an aromatic boronic acid ester, an organopalladium compound, and a basic inorganic or organic compound (and an organophosphorus compound). The curable fluorine-containing polyether composition has good processabilities such as an appropriate flowability at room temperature, and can be applied to various molding processes such as injection molding, RIM, etc.

• A new sequence isomer of AB-polybenzimidazole for high-temperature PEM fuel cells

  AbstractA new sequence isomer of AB‐polybenzimidazole (AB‐PBI) was developed as a candidate for high‐temperature polymer electrolyte membrane fuel cells. A diacid monomer, 2,2′‐bisbenzimidazole‐5,5′‐dicarboxylic acid, was synthesized and polymerized with 3,3′,4,4′‐tetraaminobiphenyl to prepare a polymer that was composed of repeating 2,5‐benzimidazole units. In contrast to previously prepared AB‐PBI, which contains only head‐to‐tail benzimidazole sequences, the new polymer also contains head‐to‐head and tail‐to‐tail benzimidazole sequences. The polymer was prepared in polyphosphoric acid (PPA) and cast into membranes using the sol–gel PPA process. Membranes formed from the new AB‐PBI were found to be mechanically stronger, possessed higher acid doping levels, and showed improved fuel cell performance, when compared to the previously known AB‐PBI. © 2011 Wiley Periodicals, Inc.
