摘要：
This invention relates to bio-based polyfunctional carboxylic acids reacted with vinyl ether compounds to form liquid vinyl-blocked bio-based polyfunctional carboxylic acids. These liquid vinyl-blocked bio-based polyfunctional carboxylic acids can be mixed with a polyfunctional vegetable oil-based epoxy resin to form a homogeneous curable coating composition. Upon curing at elevated temperature, thermoset coatings are formed which have excellent hardness, solvent resistance, adhesion, and flexibility. The invention also relates to the use of a curable coating composition comprising at least one polyfunctional vegetable oil-based epoxy resin and at least one vinyl-blocked bio-based polyfunctional carboxylic acid, which may be coated onto a substrate and cured thermally. Methods of making the vinyl-blocked bio-based polyfunctional carboxylic acids and curable coating compositions and substrates containing the same are also disclosed.
摘要（中）：
本发明涉及与乙烯基醚化合物反应以生成液体乙烯基封端的生物基多官能羧酸的生物基多官能羧酸。 这些液体乙烯基封闭的生物基多官能羧酸可以与多官能植物油基环氧树脂混合以形成均匀的可固化涂料组合物。 在高温下固化时，形成了具有优异的硬度，耐溶剂性，粘附性和柔韧性的热固性涂层。 本发明还涉及包含至少一种多官能植物油基环氧树脂和至少一种乙烯基封端的生物基多官能羧酸的可固化涂料组合物的用途，其可以涂覆在基材上并热固化。 还公开了制备乙烯基封端的生物基多官能羧酸和可固化涂料组合物的方法以及含有其的基材。
