【Abstract】 A series of novel bismaleimide resins were synthesized by copolymerization using two kinds of different bismaleimides, and adhesion agent. The chemical structures and properties of the samples were characterized by several analysis technique such as 1H NMR, IR, determination of the gelatinate temperature, TG, DTA etc. Furthermore, the curing properties have also been investigated. Many useful conclusions about the preparing conditions and the properties of these bismaleimide resins were obtained. It was found that introducing other materials into bismaleimide increased the thermal properties of bismaleimides. The satisfactory results were obtained.更多还原
