摘要: 以正丁基锂为引发剂,环己烷为溶剂,研究了四氢呋喃(THF)对聚丁二烯1,2-结构和丁苯嵌段共聚物SBS中聚丁二烯段1,2-结构含量的影响,指出在一定温度下,聚丁二烯1,2-结构含量与体系中THF的浓度有指数关系。控制体系中THF的浓度和聚合反应温度,可调节聚合产物中聚丁二烯1,2-结构含量。

Abstract: Here was studied the influence of tetrahydrofuran on the 1,2-content of polybutadiene in anionic polymerizaton for preparing polybutadiene and block copolymer SBS by using n-butyl lithium as initiator in solution of cyclohexane.The experiments showed that at given temperatures the 1,2-content of polybutadiene is a exponential function of the concentration of THF,so the 1,2-content of polybutadiene can be controlled by changing the concentration of THFat given temperature of polymerization.
