研究了三（硫代乙醇酸正丁酯）锑及其中间体硫代乙醇酸正丁酯的合成方法；首次采用热分析技术（ＤＳＣ）对添加有该产品的ｐｖｃ体系进行了热稳定机理及性能研究。结果表明：在一种新型的催化剂及混合溶剂存在下进行反应，合成产品的产率可达９０％；添加有该产品的ＰＶＣ塑料制品的起始分解温度在２８０℃以上，热稳定性大大提高。
The synthesis method of tris (n-butyl thioglycolate) antimony and its intermediate n-butyl thioglycolate was studied. The thermal stability mechanism of the pvc system added with this product was first investigated by thermal analysis (DSC) Performance study. The results show that the yield of synthesized product can reach 90% in the presence of a new type of catalyst and mixed solvent. The initial decomposition temperature of PVC plastic product added with this product is above 280 ℃ and the thermal stability is greatly improved .
