摘要：A novel series of polytriazole resins were synthesized by using aromatic diazides and N,N,N,N-tetrapropargyl-p,p-diaminodiphenylmethane (TPDDM) as raw materials. The chemical structures of the resins were characterized by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance. Rheological behavior indicates that the resins can be processed in a low-temperature region, and some of them have good solubilities in common organic solvents. Differential scanning calorimetry and FTIR results demonstrated that the polytriazole resins can be cured at 70 degrees C. The glass transition temperature (T-g) of cured resins increased with the increase in rigidity of diazide units in polymer chains and reaches up to 328 degrees C.
