| Abstract: | Polyurethanes were synthesized by condensation of diamino derivates of bis-1,3,4-oxadiazole with chloroformates, and polyurea urethanes were synthesized from diamino derivaties of bis-1,3,4-oxadiazole, diisocyanates, and ethylene glycol in a solution of dimethylformamide. Certain properties of these compounds were studied. |
