摘要：

以4,4′-二苯甲烷双马来酰亚胺、双酚A型氰酸酯和2,2-二烯丙基双酚A为基本原料制备了改性双马来酰亚胺-三嗪（BT）树脂。系统地研究了2,2-二烯丙基双酚A对BT树脂固化动力学、BT树脂的溶解性能和BT树脂固化物的热性能的影响。研究结果表明：烯丙基双酚A有效地降低了BT树脂的固化反应温度并提高了BT树脂的溶解性能。当烯丙基双酚A的加入量为20%（质量分数）时，BT树脂的固化反应峰值降至233.1 ℃；并且，其固化物的玻璃化转变温度仍然达到239.4 ℃，5%热失重温度为372.9 ℃，显示了良好的耐热性能。

Abstract:

2,2-diallyl biphenol A was used to modify the bismaleimide-triazine（BT resin）which composed of bisphenol A dicyanate ester（BCE），4,4′-bismaleimidodipphenylmethane（BMI）. The effects of 2,2-diallyl biphenol A on curing reaction，solubility and thermal property of BT resin were investigated. The results showed that 2,2-diallyl biphenol A could reduce the temperature of curing reaction and improve the solubility of BT resin. When the amount of the 2,2-diallyl biphenol A amount was 20%，The temperature of curing reaction was lowered to 233.1 ℃. Furthermore，glass transition temperature（T_g）and the temperature at which 5% of the mass volatilized of the modified BT were 239.4 ℃ and 372.9 ℃，respectively，showing that excellent thermal properties of the modified BT.
