合成了3-(4-烯丙氧基)苯基-3,4-二氢-6-(N-马来酰亚胺)-1,3-苯并(口恶)嗪(AMB),用FT-IR、1H-NMR和EA对其结构进行了表征.与传统的3-苯基-3,4-二氢-(N-马来酰亚胺)-1,3-苯并(口恶)嗪(MIB)相比,AMB的分子结构中多了一个烯丙基醚基团.AMB可溶于丙酮、甲醇、氯仿、四氢呋喃等普通有机溶剂,熔点115℃.用DSC和TGA对AMB和MIB的热聚合行为进行了比较,发现烯丙基醚官能团引入后的AMB熔点更低;于氮气条件下,150℃热处理AMB,可大幅度地降低热处理产物的再次热聚合温度,从而使其在相对低的温度下(150℃~200℃)得到充分的固化;AMB固化产物的热稳定性比MIB更好,5%热失重温度(T5)从375℃上升到449℃,800℃残炭率从56%上升到65%.
