摘要
合成了４ 种酰亚胺键扩链的胺马来酰亚胺。并采用红外光谱、核磁共振谱、差热分析对其结构和热稳定性进行了研究，结果表明扩链后的胺马来酰亚胺在树脂的固化过程中未出现明显的固化峰。与未扩链的双马来酰亚胺有所区别，所采用二胺结构不同，将在很大程度上影响固化后树脂的热稳定性。
Four kinds of amino maleimides chain extented by imide linkage were prepared. The structures of the materials were characterized by proton nuclear magnetic resonance and infra red spectroscopy, and the thermal properties of the samples were measured by thermogravimetric analysis and dynamic thermal analysis. It was found that the cured peaks of amino maleamic chain extented were disappeared during the curing procedure of resin. As distinguished from the bimaleimides chain extended using different structures of bisaminoes will affect the thermal stability of cured resin.
