The new convenient method for the synthesis of high molecular weight aromatic poly-(1,3,4-oxadiazole)s (PODs) has been proposed. These polymers were prepared by “one-pot” procedure from dicarboxylic acid and hydrazine’s salt (sulfate, phosphate) or dicarboxylic acid dihydrazides. The mixture of ionic liquid and triphenyl phosphite was used both as a a solvent and condensing agent. The polycyclization occurred at sufficiently low temperature equal to 210oC for 2 - 5 hours and resulted in obtaining film-forming PODs having inherent viscosities up to 0.9 dl/g and good thermal stability.
