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.
合成了具有不同化学结构的源自大豆油的环氧聚合物（EP）。然后用酸酐对这些聚合物进行固化，以得到源自大豆油的环氧热固性材料。对其固化动力学、热性能和机械性能进行了充分表征。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用环氧化大豆油制成的对照配方高出一个数量级以上。更重要的是，只需使用不同的EP和/或通过控制EP与酸酐的进料比例，就可以获得从软弹性体到坚韧热固性材料等一系列热固性材料。
