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
