A diamine Acenaphtohydrazinomercaptotriazole (AHTD) was synthesized in one step from acenaphthoqinone and 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole. The diamin was characterized by FTIR, 1HNMR, 13CNMR and melting point. Diamin was used to prepare novel polyamides. The low temperature solution polycondensation of diamin with tow aromatic and tow aliphatic diacid chlorides afforded diamin-containing polyamides with inherent viscosities of 0.38–0.47 dl/g in DMF at 25 °C. The polyamides were generally soluble in a wide range of solvents such as dimethylformamide(DMF), N-Methylpyrolidone(NMP), tetrachloroethane (TCE), dimethylsulfoxide(DMSO) and H2SO4. Thermal analysis showed that these polyamides were practically crustily and with Tg under 100 °C.
