摘　　要：硫醇锑稳定剂由于其耐紫外光性能很差,在存储、运输和使用方面受到很大的限制。为解决这一问题,试探性以三氯化锑和巯基酯为原料,引入抗紫外线活性基团TBP-1(2,4-二羟基二苯甲酮),合成了"晒不黑"的有机锑热稳定剂。用红外光谱对产品结构进行了确认,光敏性实验表明其7周内不变色;静态热稳定性实验结果表明其与硫醇锑热稳定剂相当。Because of its poor ultraviolet resistance , the storage , transportation and use of antimony mercaptide stabilizer was greatly limited.In order to solve this problem , a kind of synthesized organic antimony thermal stabilizer was prepared, which was light -tolerant with antimony trichloride , isooctyl thioglycollat as raw materials and TBP -1（2,4-dihydroxybenzophenone ） , with an anti-ultraviolet agent added in.The light-tolerant performance and thermal stability of product tested showed that the color of organic antimony as -synthesized was unchangeable when under the impact of direct sunlight for 7 weeks by infrared spectroscopy spectrum that was confirmed for structure of product , and the static experimental results showed that the thermal stability was nearly equivalent to antimony mercaptide.
