摘　　要：以正丁基锂为引发剂,以环己烷为溶剂,以四氢呋喃为促进剂,通过阴离子聚合反应制备了一系列窄分子量分布的聚苯乙烯,通过NMR、FT-IR、GPC等谱学手段对其进行了表征。同时分析讨论了影响分子量大小及分子量分布的因素以及窄分布聚苯乙烯的应用情况。A series of narrow molecular weight distribution PS were prepared by anionic polymerization under pro-tection of inert gas, using n-BuLi as catalyst and C6H12 as solvent. The products were characterized by NMR, FT-IR and GPC. The factors affecting the molecular weight and its distribution were also investigated. At last, the application of nar-row molecular weight distribution PS was presented.
