摘　　要：在实验研究双马来酰亚胺系列树脂耐热稳定性的基础上,讨论了双马来酰亚胺在热氧气中首先形成了正离子自由基,正离子自由基的稳定性直接影响树脂的耐热稳定性,建立起双马来酰亚胺分子结构与其耐热稳定性的关系,得到有意义的结论。In this paper.the thermal stability of bismaleimide resins hasbeen studied. The bismaleimide polar will be formed when it is exposed in thermal air and the polar's stability will affect the resins'directly. The relationship between the structure of bismaleimide and its thermal stability has been established and a reasonable conclusion has been drew.
