Some aromatic poly(amid-hydrazidesl have been synthesized b) solution polycondensation at low temperature of aromatic hydrazides x~ith aroyl dichlorides. By heating these polymers at temperatures near 300, dehydrocyclizalion occurs to give polymers containing the oxadiazole ring in the main chain. T
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
