合成了环氧亚麻酸的钙盐和锌盐，并将其用作多功能添加剂，以减少或防止环氧大豆油（ESO）与特别是聚氯乙烯（PVC）热降解过程中释放的盐酸（HCl）的反应。将这些金属环氧盐作为热稳定剂掺入到在170°C下进行热降解研究的邻苯二甲酸二异癸酯和ESO增塑的PVC共混物中。通过热重分析和PVC共混物的视觉保色性来检查这些金属环氧盐的总体性能。金属盐稳定的PVC的重量损失曲线与含有金属硬脂酸盐的共混物的重量损失曲线相当。然而，使用这些新型添加剂的增塑PVC的保色性有很大的改善。© 2014 Wiley Periodicals，Inc. J.应用聚合物Sci. 2015，132，41736。
Calcium and zinc salts of epoxidized linolenic acid were synthesized and used as multifunctional additives, to minimize or prevent the reaction of epoxidized soybean oil (ESO) with liberated hydrochloric acid (HCl) during the thermal degradation of poly(vinyl chloride) (PVC) in particular. These metal epoxy salts were incorporated as thermal stabilizers for both diisodecyl phthalate and ESO–plasticized PVC blends that underwent thermal degradation studies at 170°C. The overall performance of these metal epoxy salts was examined by thermal gravimetric analysis and visual color retention of the PVC blends. The weight loss profiles of the metal salt stabilized PVC were comparable to those of blends containing metal stearates. There were, however, vast improvements in color retention of the plasticized PVC using these novel additives. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41736.
