Abstract

New silicon-containing aromatic polyhydrazides were synthesized by low-temperature solution polycondensation reaction of bis(p-chlorocarbonylphenyl)diphenylsilane with various aromatic dihydrazides, or of bis(p-carbohydrazidophenyl)diphenylsilane with diacid chlorides. The corresponding poly(arylene-1,3,4-oxadiazole)s wvere prepared by thermal cyclodehydration in the solid state. The cyclization process takes place at temperatures in the range of 250-300 IC. The resulting silicon-containing poly(arylene-1,3,4-oxadiazole)s are soluble in common organic solvents and have good film-forming abilities. They are stable up to 420-480 'C and their glass transition temperature is in the range of 262-278C.
