A novel polytriazole resin prepared from pxylylene diazide (XDA) and N,N,N 0 ,N 0 -tetrapropargyl-p,p 0 -diaminodiphenylmethane (TPDDM) was synthesized and characterized. The resin is soluble in common solvents like acetone. The results show that the polytriazole resin can be cured at 708C. The glass transition temperature and thermal decomposition temperature of the cured resin are 218 and 3508C, respectively. The tensile and flexural strengths of the cured resin achieve 99.0 and 200 MPa, respectively.It is potential as a low cost and easy processing thermal resistant polymer matrix for advanced composite applications.
