N2 - We had been studying the synthesis of fluorine-containing polymers derived from 2,3,4,5,6-pentafluorobenzoic acid. This paper described the synthesis and characterization of novel fluorine-containing poly(arylether 1,3,4-oxadiazole)s(F-PEOs). Monomer was synthesized from hydrazine hydrate and 2,3,4,5,6-pentafluorobenzoyl chloride. F-PEOs were synthesized by nucleophilic aromatic substitution reaction at 30°C in NMP. The polymers obtained by stopping just before the gelation were all para connected linear structures confirmed by NMR. The obtained F-PEOs showed excellent solubility and afforded tough transparent films by solution casting method. They also exhibited high Tg of 157-257°C and good thermal stability, and excellent hydrophobicity due to the incorporation of 2,3,5,6-tetrafluoro-1,4-phenylene moiety.
