研究了二(2,4,6-三溴苯氧基)三苯基锑的合成方法及其性能.结果表明,使二卤三苯基锑与三溴苯酚在一定条件下反应,可得该产品,其产率达70～80%;在250℃以下的热稳定性好,对聚乙烯具有良好的阻燃效果,在不用三氧化二锑作助阻燃剂的情况下添加量仅为10 Phr,氧指数从18.5提高到26.5,且对聚乙烯的机械性能无不良好影响. The synthesis method and properties of bis (2,4,6-tribromophenoxy) triphenylantimony were studied. The results showed that the reaction of trihalbromophenol and tribromophenol under certain conditions gave the Products, the yield of 70 to 80%; at 250 ℃ below the thermal stability of the polyethylene has a good flame retardant effect, without the use of antimony trioxide as a flame retardant added in the case of only 10 Phr, the oxygen index increased from 18.5 to 26.5, with no adverse effect on the mechanical properties of polyethylene.
