摘　　要：通过氯丙基甲基硅氧烷与过量的对苯二甲酸的缩合反应制备了一种新型的含羧基硅氧烷(CCS),CCS可以同双酚A型环氧树脂固化,根据Kissinger和Crane方程,用差热分析(DSC)对CCS和环氧树脂组合物的固化性能进行了分析。分析结果表明组合物固化反应的表观活化能为71.41 kJ.mol-1,反应级数为0.911;还给出了加热速度为10℃.min-1时的固化反应方程。A new carboxyl-containing silicone （CCS） was synthesized by condensation reaction of chloropropylmethylsiloxane and excess amount of terephthalic acid. The CCS cured with a bisphenol A type epoxy resin, and the kinetics of curing reaction of the CCS/epoxy resin composites was investigated by employing differential scanning calorimetry （DSC） basing on the Kissinger＇s and Crane＇s approaches. As a result, the apparent activation energy and reaction order of the curing reaction are 71.41 kJ·mol^-1 and 0.911, respectively. The curing kinetic equation at a heating rate of 10℃·min^-1 was given.
