Abstract
This paper described the synthesis of novel fluorine-containing aromatic poly(ether sulfone)s (F-PES) by the oxidation of the corresponding fluorine-containing polythioethers (F-PTEs) derived from 2,3,4,5,6- pentafluorobenzoic acid. F-PTEs were synthesized by nucleophilic aromatic substitution reaction at relative low temperature in DMF. F-PTEs obtained by stopping just before the gelation were all para connected linear structures. The obtained F-PESs showed higher Tg than that of F-PTEs due to the introduction of sulfone units. They also exhibited excellent solubility and good hydrophobicity due to the incorporation of 2,3,5,6-tetrafluoro-1,4-phenylene moiety.
