摘要：A novel low-temperature curing polytriazole resin was prepared from a triazide and a tetraalkyne and characterized. The resin can be cured at 70 degrees C. The glass transition temperature T-g and thermal decomposition temperature T-d5 of the cured resin with the molar ratio of azide to alkyne group [A]/[B] = 1.0:1.0 reached 324 and 355 degrees C, respectively. The study on the curing kinetics of the resin shows that the apparent activation energy of the curing reaction is 93 kJ mol(-1). The flexural strength of the cured resin reached 137.6 MPa at room temperature and 102.6 MPa at 185 degrees C. Copyright (c) 2007 John Wiley & Sons, Ltd.
