摘要：

Polyhydrazides with parabanic structures were prepared by polycondensation between a new monomer containing a preformed parabanic ring, viz. 1,3 p(bis-chloroformylphenyl) parabanic acid and dihydrazides. By thermal cyclization with polyphosphoric acid, the polyhydrazides were converted to poly(1,3,4-oxadiazole)s with parabanic structures. The films obtained from these polymers exhibit electrical insulating properties and good thermal stability.
