摘　　要：采用二烯丙基双酚A(DP)与乙烯基橡胶对两种结构类型双马树脂进行增韧。探讨了乙烯基橡胶用量对改性树脂的力学性能、耐热性能及玻璃化转变温度的影响,确定当乙烯基橡胶用量为5%(占双马树脂)时,改性树脂具有较好的综合性能,较未增韧前有大幅提高。此时,冲击强度为23.17kJ/m2,GIC值为338.5J·m-2,玻璃化转变温度为241℃,5%热失重温度约在420℃。同时,通过SEM观察其断面的微观形貌为典型的韧性破坏。Two types of bismaleimide are toughened with ortho-diallyl bisphenol A and vinyl rubber. The effect of vinyl rubber content on the mechanical properties, heat resistance and glass transition temperature of modified resin is discussed. The modified resin has better performance compared to the one not toughened when the content of vinyl rubber is 5% of the bismaleimide resin. At this point, the impact strength is 23.17kJ/m2 and the GIC value is 338.5J·m-2. The glass transition temperature is 241℃ and the temperature of 5% weight loss is about 420aC. The micro morphology of the cross section shows a typical toughness destruction observed by SEM.
