Polymers synthesized directly from plant oils such as castor oil usually exhibit poor mechanical properties and cannot be reprocessed due to the soft, highly cross-linked and permanent cross-linking structures. Herein, we report a novel approach to synthesize high performance and malleable polymer networks, namely poly(ester amide) vitrimers, from castor oil via melt condensation polymerization with sebacic acid, polyamide 1010 monomer salt and 4-aminophenyl disulfide. 4-Aminophenyl disulfide with excellent thermal stability is applicable for high temperature polymerization and endows the poly(ester amide) network with malleability. Polyamide 1010 segments introduced by polyamide 1010 monomer salt endow the poly(ester amide) network with improved and tunable mechanical properties. This investigation demonstrates a new powerful strategy for developing high performance and reprocessable polymer networks from plant oils.

通过熔融缩聚合成可延展和可持续的聚酯（酯酰胺）网络

由植物油（如蓖麻油）直接合成的聚合物通常显示出较差的机械性能，并且由于其柔软，高度交联和永久性的交联结构而无法进行再加工。在这里，我们报告了一种新的方法，可以通过蓖麻油与癸二酸，聚酰胺1010单体盐和4-氨基苯基二硫化物的熔融缩聚反应，从蓖麻油中合成高性能和可延展的聚合物网络，即聚（酯酰胺）三聚物。具有优异热稳定性的4-氨基苯基二硫化物适用于高温聚合反应，并赋予了聚（酯酰胺）网络延展性。由聚酰胺1010单体盐引入的聚酰胺1010链段赋予聚（酯酰胺）网络以改进和可调的机械性能。
