Abstract A new epoxy curing system, combining amine and maleimide functionality into a single molecule, was introduced to broaden current state of the art as regards epoxy, amine and maleimide systems. Curing agent aminomaleimide was tested in the curing process of several aromatic and aliphatic epoxies. Prepared mixtures in different weight (molar) ratios were investigated by nonisothermal differential scanning calorimetry to study and compare curing kinetics of different epoxies. The apparent activation energy was determined by Kissinger method, while Friedman method accompanied by Malek statistical approach was used in confirming the autocatalytic nature of epoxy curing and additional maleimide polymerization at the excess amount of aminomaleimide. Thermo-mechanical properties were determined by dynamic mechanical analysis and the effect of aminomaleimide curing agent compared to curing agent containing only amino functional groups was evaluated. Aminomaleimide showed improvement in the glass transition temperatures and higher char yields due to the involvement of maleimide moiety in the curing process. In overall, aminomaleimide showed the positive one-molecule joint effect of the amino group, behaving as an accelerator, and maleimide group, a mechanical properties enhancer.

氨基马来酰亚胺中胺和马来酰亚胺官能团对环氧树脂固化动力学和力学性能的共同作用

摘要 引入了一种新的环氧固化体系，将胺和马来酰亚胺官能团结合到一个分子中，以拓宽当前环氧树脂、胺和马来酰亚胺体系的技术水平。在几种芳香族和脂肪族环氧树脂的固化过程中测试了固化剂氨基马来酰亚胺。通过非等温差示扫描量热法研究制备的不同重量（摩尔）比的混合物，以研究和比较不同环氧树脂的固化动力学。表观活化能由 Kissinger 方法确定，而 Friedman 方法和 Malek 统计方法用于确认过量氨基马来酰亚胺时环氧树脂固化和附加马来酰亚胺聚合的自催化性质。通过动态力学分析确定热机械性能，并评估氨基马来酰亚胺固化剂与仅含有氨基官能团的固化剂相比的效果。由于马来酰亚胺部分参与固化过程，氨基马来酰亚胺显示出玻璃化转变温度的改善和更高的炭产率。总的来说，氨基马来酰亚胺表现出氨基作为促进剂和马来酰亚胺基团作为机械性能增强剂的积极的单分子联合效应。
