摘　　要：使用差动热分析仪 ,以等速升温热固化和等温热固化方式研究了环氧化聚丁二烯及双酚A型环氧树脂在α 甲基 四氢苯酐、顺酐、酸酐 70 # 等固化剂作用下的热固化行为 ,确定了LEPB MBA体系固化反应的活化能在71.90～ 75 .0 3kJ·mol-1之间。实验证明 。The curing characteristics and kinetics of liquid epoxidized polybutadiene(LEPB) with MBA,MA and A70 # were studied by curing of isothermal temperature and uniform temperature rise by use of DSC,and the activation energies of reactions between 71.90～75.03kJ·mol -1 were determined.The results proved that there are distinct difference of curing behaviors between LEPB and epoxy resins of diphenylpropan type.
