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. Model reactions de

## Abstract Novel poly(arylene ether)s with a rigid and zigzag 4,4β³β__o__βterphenyldiyl structure, introduced into the polymer backbone were synthesized by nucleophilic displacement reaction of 4,4β³βdihydroxyβ__o__βterphenyl with several activated aromatic dihalides in virtually quantitative yields
A series of new high molecular weight poly(arylene ether)s containing the 1,2-dihydro-4-phenyl(2H)phthalazinone moiety have been synthesized. The inherent viscosities of these polymers are in the range of 0.33-0.64 dL/g. They are amorphous and readily soluble in chloroform, DMF, and DMAc. The glass
Electrochemical doping processes of aromatic poly( 1,3,4-oxadiazole)s in acetonitrile/Bu,NBF, have been studied to characterize the charge and discharge properties of these polymers. Cyclic voltammograms were measured of thin poly(arylene-1,3,4-oxadiazole) films on glassy carbon, Pt and IT0 glasses.
