摘　　要：通过非等温DSC对自制的酚醛氰酸酯树脂进行了固化动力学方面的研究，通过T～β外推法得到树脂凝胶化温度为211．00℃，固化温度为246．67℃，后固化温度为300．78℃。通过Kissinger方程求解树脂固化反应表观活化能为△E=74．14kJ／mol，碰撞因子为A=4．99×10^6。通过Crane方程求得固化反应级数为n=0．920。The kinetics of the curing reaction of novolac cyanate ester resins was studied by DSC. The activity energy, reaction order and frequency factor of the curing reaction of the resin were obtained that △E= 74.14kJ/mol, A = 4.99 × 10^6 and n = 0.920.At the same time, the gel point, setting point,post cure temperature of this resin we got is 211.00, 246.67 and 300.78 ℃.
