摘　　要：双马来酰亚胺树脂(BMI)是一种常见的反应型聚酰亚胺,具有优异的综合性能,但其预聚物黏度较高而且固化物脆性较大,因此,需要对其进行改性,拓展BMI的应用范围。在介绍BMI性能的基础上,对其常见的改性方法进行了综述,重点介绍了分子链设计改性法中的烯丙基化合物改性、扩链改性、杂原子及官能团改性,以及共混改性法中的纳米粒子改性、有机化合物改性和聚合物改性等方法。研究表明,目前对于BMI的改性重点已经从传统的性能提升,逐渐发展为BMI结构设计调控和合成技术优化,并取得了较大的成果。此外,BMI新的改性方法工业化成为其未来的重点研究方向。Bismaleimide resin(BMI)is a common reactive polyimide with excellent comprehensive properties,but the prepolymer viscosity is too high and the brittleness of cured material is large.Therefore,it is necessary to be modified to expand the application range of BMI.On the basis of introducing the BMI performance,the current common modification methods of BMI are reviewed,including the molecular chain design modification method,such as allyl compound modification,chain extension modification,impurity atoms and functional groups of modified method;as while as the blending modification method,such as nanoparticles modified method,organic compound modification and the polymer modification,etc.A large number of literature shows that the current focus of BMI modification has gradually developed from traditional performance improvement to BMI structural design regulation and synthesis technology optimization.In addition,the industrialization exploration of new modification methods for BMI will become a research focus in the future.
