    Studies of Influence of Additive on BDM''''s Synthesis and Properties

    • 摘要: 采用丙酮为溶剂并在反应前向体系中添加少量醇类添加剂的方法,合成了二苯甲烷双马来酰亚胺(BDM),同时与无添加剂体系作了比较。研究了添加剂及其用量对BDM产物的收率,副产物和各种性能的影响,用IR,DSC,SEM和GT等方法对BDM进行了测试和表征,结果表明,有醇类添加剂时BDM产物的基本化学结构没有变化,但反应的收率下降,副产物含量减少,物态有所变化,溶解度略有增加,凝胶化时间变短,热聚合(固化)速率加快,表观活化能下降,热聚合反应的活性有一定程度提高。
