| 摘 要： | 在二硫代苯甲酸和偶氮二异丁腈引发下,苯乙烯与溴代苯乙烯发生可逆加成断裂链转移自由基(RAFT)共聚,所得共聚物与正丙基硫化钠在N-甲基吡咯烷酮中发生亲核取代反应,再与碘甲烷作用,成功制备了新型硫醚型硫掺杂聚苯乙烯。分别采用红外光谱、核磁共振氢谱、元素分析和凝胶渗透色谱对聚合物化学结构、硫原子掺杂量和相对分子质量进行了表征。结果表明,成功合成了硫掺杂聚苯乙烯,硫原子的掺杂量可控且掺杂均匀。该类硫掺杂聚苯乙烯有望为惯性约束聚变(ICF)靶研究提供更多的诊断信息,对ICF靶科学研究有着重要的现实意义。

| Abstract: | A copolymerization of 4-bromostyrene and styrene was conducted via the reversible addition-fragmentation chain transfer(RAFT) method,using AIBN as initiator and dithiobenzoic acid as chain transfer agent.After sequence reaction of the copolymer with sodium n-propylthiolate via nucleophilic substitution and methyl iodide,a new type of sulfide-type sulfur-doped polystyrene was prepared successfully.The structures of the polymer were confirmed by means of IR and ~1H NMR The molecular weight was measured by gel... |
