采用二烯丙基双酚A(DABPA)对4,4'-双马来酰亚胺基二苯甲烷(BMI)进行改性，然后与环氧树脂和4,4'-二氨基二苯砜（DDS）共混制得覆铜板，并对改性BMI树脂和覆铜板分别进行了结构表征和性能测试。结果表明：研制的覆铜板阻燃等级达到V-0，并具有较好的介电性能、耐热性能以及力学性能。
A copper clad laminate was prepared by blending 4, 4'-diphenyl bismaleimide(BMI) modified by diallyl bisphenol A, epoxy resin and diamine(DDS), and the structure of the modified BMI and the properties of the copper clad laminate were studied. The results show that the copper clad laminate has good dielectric properties, thermal stability and mechanical properties, and the flame retardancy grade reaches V-0.
