以松香酸和异山梨酯为原料，分别合成了两种环状结构的脂肪族环氧固化剂。用二缩水甘油酯醚双酚A （DER331）进行固化，并对固化树脂的最终性能进行了研究。为了比较，以对苯二甲酸为原料合成了含平面苯环的石油基固化剂。利用傅里叶变换红外光谱和核磁共振对所合成固化剂的化学结构进行了表征。通过热重分析和动态力学分析研究了固化后环氧树脂的最终性能。重点从形状固定性、形状恢复和形状恢复时间等方面研究了环形结构对其形状记忆性能的影响。©2016 Wiley期刊公司j:。变异较大。科学通报，2016,33(3):444 - 444。
Two kinds of aliphatic epoxy curing agents containing ring structures were synthesized from rosin acid and isosorbide, respectively. They were cured with diglycidyl ether bisphenol A (DER331) and the ultimate propertied of the cured resins were investigated. For comparison, the petroleum-based curing agent containing planar benzene ring was synthesized from terephthalic acid. The chemical structures of the synthesized curing agents were identified by Fourier transform-infrared and H-nuclear magnetic resonance. The ultimate properties of the cured epoxy resins were investigated by thermogravimetric analysis and dynamic mechanical analysis. Especially, the effects of ring structure on their shape memory properties were studied in terms of shape fixity, shape recovery, and shape recovery time. © 2016 Wiley Periodicals, Inc. J. Appl.
