摘要：合成了２，２′－亚甲基－二（４－甲基－６－烯丙基）苯酚，用它增韧二苯甲烷型双马来酰亚胺树脂，对改性双马来酰亚胺预聚物的凝胶化时间、ＤＳＣ分析和ＦＴ－ＩＲ分析的研究，得到了改性双马来酰亚胺树脂体系的固化条件为１８０℃／１ｈ＋２００℃／２ｈ＋２５０℃／４ｈ；热重分析法研究了双马来酰亚胺树脂体系的热分解反应动力学，得出体系的热分解反应活化能为２７４．４ｋＪ／ｍｏｌ；改性双马来酰亚胺树脂体系常温弯曲强度为１２４ＭＰａ，弯曲模量为３７７４．６ＭＰａ，２５０℃下弯曲强度保留６９％，弯曲模量保留７８％。
2,2′-methylene-bis[4-methyl-6-(2-propenyl)]phenol was synthesized and was used to toughen methylene dianiline bismaleimide resin. The curedcondition of modified bismaleimide resin was studied by gel time of prepolymer under various temperature, DSC and FT-IR analysis, and the curing cycle of the modified bismaleimide was 180 ℃/1 h+200 ℃/2 h+250 ℃/4 h; the kinetic study of thermal degradation for the modified bismaleimide resin was also researched by thermal gravity analysis. The activation energy of the thermal degradation reaction is 274.4 kJ/mol; the flexural strength of modulus of the modified bismaleimide resin are 124 MPa and 3774.6 MPa at 25 ℃, and are retained 69% and 78% at 250 ℃, respectively.
