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.

New polyarylene ethers containing rigid naphthalene, pyridine and quinoline moieties have been prepared by the nucleophilic displacement of suitable aromatic dihalides with corresponding potassium bisphenates. The reaction was carried out using DMAc or DPS as solvent. The chemistry and thermal prope
Poly(arylene ether)s ( 3), (4) containing pendant benzoyl groups as precursors for novel polyxanthenes ( 7), (8) were prepared by nucleophilic substitution reaction of 2,5-difluoro-4-benzoylbenzophenone ( 1) or 2,5-difluoro-4-(4-dodecylbenzoyl)-4dodecylbenzophenone ( 2) with hydroquinone derivatives
A series of novel poly(arylene ether ketone)s were synthesized from the reaction of hydroquinone and 4-(4-hydroxyphenyl)-2,3-phthalazin-1-one with 4,4Π-difluorobenzophenone in N-cyclohexylpyrrolidinone containing anhydrous potassium carbonate. The polymers exhibited high glass transition temperature
