摘　　要：以巯基乙酸和氢氧化钡为原料 ,合成了巯基乙酸钡 [简称Ba(TG) ]。对产品进行了红外光谱分析及其物化常数检测 ,并将它与硫醇锑Sb(IOTG) 3 复配添加到聚氯乙烯 (PVC)中 ,通过热老化箱实验法、刚果红试纸法及热重法等多种方法对其PVC复配系统的热稳定性能进行了综合评价。结果表明 ,巯基乙酸钡与硫醇锑之间有着显著的协同作用 ,它不仅能降低硫醇锑在PVC热稳定剂中的用量 。Barium thioglycolate had been synthesized based on mercaptoacetic acid and barium hydroxide. Some physical and chemical constants and infrared spectra were tested. It was incorporated into PVC with antimony tris(isooctyl thioglycolate)[Sb(IOTG) 3], and the thermal stability was comprehensively studied by ageing oven method, Congo red method and TG. It is shown that Ba(TG) has remarkable synergism with antimony mercapitide,improves the long-term stabilizing effect of antimony mercaptide stabilizer effectively and reduce the amount of antimony compound.
