Abstraet--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

## Abstract High molecular weight poly‐__N__‐alkylhydrazide‐oxadiazoles have been prepared in poly‐phosphoric acid by alkylation of poly‐1,3,4‐oxadiazole which was synthesized from terephthalic acid and hydrazine sulfate. Various kinds of reagents having an alkoxy group were used as alkylating agen
