摘　　要：以二苯甲烷双马来酰亚胺和邻－二烯丙基双酚Ａ为共聚单体，制成了增韧的双马来酰亚胺（ＢＭＩ）树脂．并测定了树脂的各种性能．对影响因素作了探讨．还研究了双马来酰亚胺及ＢＭＩ／二烯丙基双酚Ａ固化树脂的热稳定性，提出了交联产物的热分解历程．A toughened bismaleimide resin was made from his (4, 4'- maleimidodiphenyl)-methane and 2, 2-bis (4-hydroxy-3-allylphenyl) propane. The properties for the resins were determined and the effect of some factors on the properties was investigated. The results showed that the bismaleimide resinis necessarily used as not only a resin matrix for advanced composite materials but also an insulation material. The thermal stability for the crosslinked N, N'.4,4'-diphenylmethane-bbismaleimide and cured bismaleimide / 2,2'-diallyl bisphenol A resin was studied and a degradation mechanism for the cured bismaleimide was suggested in present paper.
