用环氧树脂和二烯丙基双酚A（DP）合成了3种新型烯丙基酚氧树脂，测试了该树脂改性双马来酰亚胺（BMI）树脂体系的力学性能和热性能及黏度特性，探讨了后处理对改性树脂性能的影响。结果表明，改性树脂具有良好的2韧性和耐热性，冲击强度达到了22.31 kJ/m ，HDT仍有224℃，后处理使得体系耐热性大大提高，韧性略有降低。

In this paper, a series of novel allyl phenol epoxy resins was successfully prepared with epoxy resins (EP) and 3,3’-diallyl-bisphenol A (DP) to modify the bismaletimide (BMI) resins.Mechanical property,viscosity characteristics and thermal property of the BMI resins modified with aforesaid phenol epoxy resins were tested.Then we discusssd the the impact of post-processing on the system.The impact toughness and heat distorsional temperature of the modified BMI resin were-222.31 kJ?m and 224℃,respectively.That shows the modified BMI resins have good toughness and heat resistance.The post processing obviously improved the heat resistance of the modified BMI resins and slightly reduced their toughness.
