A series of new poly(l,3,4-oxadiazole-amide)s containing pendent imide groups has been synthesized by solution polycondensation of aromatic diamines containing preformed 1,3,4-oxadiazole rings with two diacid chlorides containing imide rings. These polymers were also prepared by the reaction of the
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
