| 摘 要： | 本文报道了在RLi-配位体络合体系中阴离子聚合方法合成窄分布聚苯乙烯的研究结果.在己烷、庚烷、甲苯等溶液中合成分子量范围为10~2～10~3。的窄分布聚苯乙烯(MWD<1.10)时,以鹰爪豆矸、N,N,N’,N’-四甲基乙二胺为配位体的络合体系,聚合操作简便,效果非常好.在非极性溶剂中加一定比例的THF以后,该体系也能合成分子量范围为10~4～10~5的窄分布聚苯乙烯.

| Abstract: | The synthesis of narrow distribution polystyrene by anionic polymerization in RLi-ligand complex system was investigated. It is found that RLi-(- )-sparteine and RLi-N,N,N' ,N'-tetram-ethylethylenediamine as the ligand complex systems are effective for preparation of narrow distribution of polystyrene with molecular weight in the range of 102 - 105 through using hexane, heptane and toluene as solvents respectively. By adding THF to the above systems we also obtained the narrow distribution polystyrene with molecular weight in the range of 104-105. |
