摘　　要：以一种简便的方法制备了环氧基保留完好的高纯度环氧脂肪酸钙,研究发现环氧脂肪酸钙对聚氯乙烯(PVC)的热稳定作用类似于硬脂酸钙,具有长期热稳定性的特征;但其热稳定效能明显优于后者,且具有较好的初期着色性。High purity calcium epoxidized fatty acid salt with well preserved epoxy groups was synthesized by a simple and convenient method. The heat stabilization of calcium epoxidized fatty acid salt on PVC was similar to that of calcium stearate on PVC, which was better than that of the latter in long-term stability, and had good initial colorability.
