烯丙基化合物改性双马来酰亚胺树脂的研究进展

双马来酰亚胺(BMI)树脂以其优异的机械和热稳定性能广泛用于航空航天等领域,但纯BMI熔点高、韧性和溶解性差,不能满足实际使用要求,必须对其进行改性。探讨了烯丙基化合物改性BMI的反应机理,包括"Ene"反应、Diels-Alder反应以及体系中可能存在的其他反应;并分别概述了二烯丙基双酚A(DABPA)、含硼烯丙基化合物、烯丙基酚醛树脂、烯丙基酚氧树脂及其他烯丙基化合物改性BMI体系的研究进展和改性效果。

Research progress of bismaleimide resin modified by allyl compounds

The bismaleimide(BMI) resin with excellent mechanical properties and thermal stability is widely used in aircraft and aerospace industry,but the pure BMI with high melting point as well as low toughness and solubility can’t satisfy demands of practical application. So BMI need be modified. The reaction mechanism of BMI modified by allyl compounds was discussed,including "Ene" addition reaction,Diels-Alder reaction and some other proposed reaction. The research progress and effect of BMI systems modified by allyl compounds,including diallyl bisphenol A(DABPA),allyl compounds containing boron,allyl phenolic resin,allyl phenoxy resin and other allyl compounds,were introduced respectively.
