介绍了部分溴代聚苯乙烯（Ｂｒ－ＰＳ）靶材料的制备与特性。内容涉及市售聚苯乙烯（ＰＳ）的制备型凝胶渗透色谱（ＧＰＣ）分级，窄相对分子量分布ＰＳ与Ｂｒ２间的亲电反应及其动力学特性，Ｂｒ－ＰＳ粗产物的纯化，以及Ｂｒ－ＰＳ样品的结构与性能分析。所制备的Ｂｒ－ＰＳ聚合物质均相对分子量Ｍｍ约８万－１５万，相对分子量分布ｄ＜１．１，掺溴原子百分含量为０５％－４．５％，能较好地满足激光掺杂靶丸的制备要求。文中还简要讨论了材料的应用。
The preparation and characteristics of some brominated polystyrene (Br-PS) target materials are introduced. It deals with preparative gel permeation chromatography (GPC) fractionation of commercially available polystyrene (PS), electrophilic reaction between narrow relative molecular weight distribution PS and Br2 and its kinetic properties, purification of Br-PS crude product, and Br Structure and Performance Analysis of -PS Samples. The prepared molecular weight of the Br-PS polymer is about 80,000-115,000, the relative molecular weight distribution d <1.1, the percentage of bromine atoms doped is 05% -4.5%, which can better meet the requirements of laser doping Preparation of hybrid pills target. The article also briefly discusses the application of materials.
