摘要：
A series of new poly(1,3,4-oxadiazole-imide)s has been synthesized from various aromatic dihydrazides and diacid chlorides which contain both imide and hexafluoroisopropylene units. The diacid chlorides were reacted with aromatic dihydrazides to prepare poly(hydrazide-imide)s which were subsequently cyclodehydrated in their solid state to give poly(1,3,4-oxadiazole-imide)s. The new polymers were soluble in polar solvents and were stable up to 450-480 degrees C in nitrogen, as determined by thermogravimetric analysis.
