合成了源自大豆油的具有不同化学结构的环氧聚合物（EP）。然后用酸酐固化这些聚合物，产生大豆油衍生的环氧热固性材料。固化动力学、热学和机械性能得到了很好的表征。由于每个环氧聚合物链具有高环氧官能度，这些热固性材料的拉伸强度比含有环氧化大豆油的对照配方高一个数量级。更重要的是，通过使用不同的EP和/或通过控制EP与酸酐的进料比，可以简单地获得从软弹性体到坚韧热固性材料的热固性材料。
Epoxy polymers (EPs) derived from soybean oil with varied chemical structures are synthesized. These polymers are then cured with anhydrides to yield soybean‐oil‐derived epoxy thermosets. The curing kinetic, thermal, and mechanical properties are well characterized. Due to the high epoxide functionality per epoxy polymer chain, these thermosets exhibit tensile strength over an order of magnitude higher than a control formulation with epoxidized soybean oil. More importantly, thermosetting materials ranging from soft elastomers to tough thermosets can be obtained simply by using different EPs and/or by controlling feed ratios of EPs to anhydrides.
