摘　　要：研究了苯并 口恶嗪二苯醚树脂固化时的体积收缩率、固化温度和固化焓变等。结果表明 ,这类新型树脂在室温下 ,固化收缩小于环氧树脂。在高温下 ,固化收缩率与环氧树脂相当。Curing shrinkage, temperature and curing enthalpy of benzoxazine based on diphenyl oxide resin were investigated. The results show that the novel resin has a cure shrinkage lower than that of typical epoxies in room temperature; that the cure shrinkage of the resin approximates to that of epoxies in high temperature, and that the cure temperature and enthalpy of the resin are affected greatly by heating rates and catalysts.
