Poly(1, 3, 4-Oxadiazole-Amide)s Containing Pendent Phenoxy Groups:

摘要: A series of new poly(1, 3, 4-oxadiazole-amide)s have been synthesized by solution polycondensation aromatic diamines containing preformed 1, 4-oxadiazole rings with phenoxyterephthalic diacid chloride or the reaction same p-aminobenzhydrazide resulting in a polyhydrazide-amide which was cyclodehydrated to corresponding oxadiazolic structure. The polymers were soluble partially polar amidic solvents, stable up 375–400 °C air and had glass transition temperature range 225–272 °C.
