The results reveal that introducing bismaleimide into the cured system can improve the heat distortion temperature, flexural strength at high temperature and dielectric properties. In addition the reaction scheme of bismaleimide is mainly the self-polymerization but not copolymerization with epoxy group.

研究结果认为体系中引入双马来酰亚胺可提高热变形温度、热态强度和介电性能，双马来酰亚胺在固化中主要是自聚而不是和环氧基共聚。
