摘　　要：以三溴苯酚、四氯化硅及2,3-二溴丙醇为主要原料合成新型硅、溴协同高效阻燃剂二(2,3-二溴丙氧基)二(三溴苯氧基)硅烷。探讨了加料顺序、溶剂、反应温度、反应时间及物质的量比等对产率的影响,并采用FT-IR、1 H-NMR和极限氧指数对产品的分子结构及性能进行了表征。结果表明:该产品热稳定性好,应用于聚氯乙烯等材料有良好的阻燃、增塑和成炭防熔融滴落效果。The bis（2,3-dibromopropoxy） bis（tribromophenoxy） silane is a novel and efficient synergistic flame re- tardants having two elements of silicon and bromine, which is mainly synthesized by tribromophenol, silicon tetrachloride and 2,3-dibromo propanol. The effect of charging order, solvent, reaction temperature, reaction time and amount ratio of substance on the reaction yield was also discussed. The molecular structures and properties of product were characterized by FTIR,1 H-NMR and LOI technique. Experiments showyh that the thermal stability of product was well. Products used in PVC and other materials had a good effect on antiflaming,plasticizing,charring and anti-dripping.
