We report an atom-efficient approach to the preparation of sustainable polyesters and their corresponding thermosetting resins (RESINs) from renewable plant oils. Specifically, a diol monomer, oleic acid diethanol amide (OADEA), was derived from high oleic soybean oil (HOSBO) via a powerful amidation reaction. A series of OADEA-derived polyesters were prepared by condensation polymerization of this diol monomer with four different diacids. These polyesters were then epoxidized and cured using anhydrides with the aid of organocatalytic amines, yielding HOSBO-derived RESINs. Both thermal and mechanical properties of RESINs were dictated by the main-chain structures. The curing formulations and conditions were tested extensively to obtain the optimal mechanical properties of thermosetting resins, ranging from plastic to elastomeric properties. Both polyesters and RESINs were fully degradable under basic conditions.

高油酸大豆油衍生的可再生原子高效聚酯和热固性树脂

我们报告了一种从可再生植物油中制备可持续聚酯及其相应的热固性树脂（RESINs）的高效方法。具体来说，二醇单体油酸二乙醇酰胺（OADEA）是通过高油酸大豆油（HOSBO）通过强大的酰胺化反应。通过该二醇单体与四种不同的二酸的缩聚反应，制备了一系列OADEA衍生的聚酯。然后在有机催化胺的帮助下，使用酸酐将这些聚酯进行环氧化和固化，从而制得HOSBO衍生的树脂。树脂的热和机械性能都由主链结构决定。对固化配方和条件进行了广泛的测试，以获得热固性树脂从塑料到弹性体的最佳机械性能。聚酯和树脂在基本条件下均可完全降解。
