摘要
以正丁基锂为引发剂,以经过处理的工业级环己烷为溶剂、四氢呋喃为促进剂,用阴离子聚合的方法,在常压和惰性气体保护条件下,制得一系列千克级窄分子质量分布的聚苯乙烯,利用IR、1H-NMR、GPC等技术对聚苯乙烯产物进行了表征,分析了影响聚苯乙烯的分子质量及分子质量分布的因素.
A series of narrow molecular mass distribution polystyrene (PS) were prepared by anionic polymerization under the protection of inert gas, using n-buLi as initiator, C6H12 as solvent with simple treatment, THF as promoting agent. The products were characterized by 1H-NMR, IR and GPC, and the main factors affecting on the molecular mass and its distribution of PS were also discussed.
