Starting from some new 2,5-disubstituted-1,3,4-oxadiazole difluorides, synthesized by cyclocondensation of dihydrazides with 4-fluorobenzoic acid, novel poly(arylene ether)s were prepared by halo displacement polymerizations with bisphenol A in the presence of potassium carbonate.

## Abstract Poly(arylene ether oxadiazole) telechelics with fluorine and hydroxyl end groups were synthesized by nucleophilic substitution polymerizations of 2,5βbis(4βfluorophenyl)β1,3,4βoxadiazole monomer with bishydroxy compounds containing ο£ΏC(CH~3~)~2~, ο£ΏC(CF~3~)~2~ and ο£ΏSO~2~ο£Ώ groups.
