| 摘 要： | 研究了二烯丙基双酚A（DBA）催化改性酚醛型氰酸酯树脂（cy-5），通过差示扫描量热法（DSC）、热重分析（TG）、冲击性能和动态热机械分析（DMA）测试，分析了改性树脂的热性能和力学性能。研究表明：DBA对cy-5有催化和增韧的双重作用，当DBA的添加量为5%（质量分数）时，催化效果最为明显，含10% DBA的改性树脂固化物的冲击强度达到7.41 kJ/m2，改性树脂固化物的玻璃化转变温度（Tg）和储能模量（E'）均有所降低，但幅度不大。

| Abstract: | Effects of diallyl bisphenol A(DBA) on catalyzing the thermal curing of novolac cyanate ester resin(cy-5) were studied. Thermal and mechanical properties of DBA catalyzed novolac cyanate ester resins were characterized by DSC，TG，impact performance and DMA test. The results showed that DBA can catalyze the curing reaction and toughen the cured resin with dual function，the 5% DBA-catalyzed novolac cyanate ester resin exhibits the best catalytic effect，the impact strength of the cured resin modified by 10% DBA is 7.41 kJ/m2，and the glass transition temperature and storage modulus of the cured resin modified by DBA both decrease slightly. |
