Abstract
Ortho-, meta, and para-nitrobenzoyl derivatives of the dihydrazides of succinic, glutaric, adipic, and azelaic acids are prepared, from which are obtained nitro and amlno derivatives of bis-1,3,4- diazole. Various conditions for synthesizing these compounds are investigated. A series of polyureas is obtained by reacting diamino derivatives of bis-1,3,4-oxadiaole with diisocyanates, and some of their properties are investigated.
