Abstract:

In order to obtain bismaleimide resin with better property,O,O’diallybisphenol A(BA) and O,O’diallybisphenol S(BS) were used together as modified agent of bismaleimide resin,the influence of the ratio of BA/BS and  cure posttreatment time on modified BMI was investigated in this paper.The thermal properties of modified bismaleimide resin were investigated primarily by Dynamic Mechanical Analysis (DMA).The results show that the glass transition temperature (Tg) of the cast prepared with BA/BS=7/3(molar ratio) can reach 349.5℃,and the higher Tg of cast can be achieved by prolonging cure posttreatment time.
