A new kind of polytriazole resins were prepared from a triazide and a dialkyne compounds and characterized. These resins can be cured at 80 degrees C. The curing process for a resin was traced by FT-IR. The glass transition temperature T-g and thermal decomposition temperature T-d5 of the cured resin with the molar ratio of azide group to alkyne group [a]/[b]=1.0:1.0 reach 216 degrees C and 360 degrees C, respectively. The flexural strength of the cured resin and its glass fiber reinforced composite arrive at 183.6 MPa and 963.4 MPa, respectively. The resin would be a good candidate for the matrices of advanced composites.
