摘　　要：利用傅里叶变换红外光谱法研究双马来酰亚胺树脂固化过程中的结构变化,认为双马来酰亚胺树脂固化反应分两步进行:第一步是低温下的“ENE”反应;第二步是高温下的Diels-Alder反应。树脂第一步固化反应达到一定程度后,要进一步提高固化反应程度,必须提高温度才能使第二步固化反应发生。The structural changes in the curing process of bismaleimide resin were studied by means of FT-IR, which indicate that the curing reaction is in two steps. The first step is 'ENE' reaction at low temperature and the second step is 'Diels - Alder' reaction at high temperature. The cure degree is increased effectively with raising the curing temperature, not with adding the curing time.
