摘　　要：以正丁基锂为引发剂 ,环己烷为溶剂 ,四氢呋喃为促进剂 ,采用阴离子聚合法 ,在常压和惰性气体条件下 ,制备了一系列千克级窄摩尔质量分布的PS。用1HNMR、IR、GPC其进行了表征。A series of narrow molecular weight distribution PS was prepared by anionic polymerization under the protection of inert gas,with n BuLi as initiator,C 6H 12 as solvent,and THF as accelerating agent The products were characterized by 1H NMR ,FT IR and GPC,and the main factors that had effect on the molecular weight and its distribution of PS were also discussed
