三异丁基铝
Barium salt of di(ethylene glycol) ethylether(BaDEGEE) and barium salt of tetrahydrofurfuryl alchol(BaTHFA) were synthesized in this paper,and then star-shaped high trans-1,4-polybutadiene(s-HTPB) was synthesized with organic barium/triisobutylaluminum/multilithium(Ba/Al/Li) as the initiation system and cyclohexane as the solvent.
论文合成了二乙二醇单乙醚钡(BaDEGEE)和四氢糠醇钡(BaTHFA),并采用有机钡-三异丁基铝-多锂(Ba/Al/Li)复合引发体系,以环己烷为溶剂,利用阴离子聚合法制备星型高反式-1,4-聚丁二烯(s-HTPB)。
