本文阐述了ｎ－ＢｕＬｉ／ｔ－ＢｕＯＫ引发体系溶液了苯共聚的“多活性种互换”模型； 重点分析了钾活性种在本体系中的动力学行为；指出钾活性种不仅增长苯乙烯而且增 长丁二烯；对增长丁二烯来说，丁苯共聚时钾活性种的活性是锂活性种的九倍以上； 本文推导了共聚组成方程式，指出了表观竞聚率的复杂性，并根据我们的实验结果， 计算了几种情况的平均表观竞聚率。
In this paper, the model of “multi-active species exchange” of benzene copolymerization in n-BuLi / t-BuOK initiator system was described. The kinetic behavior of potassium active species in this system was mainly analyzed. Butadiene increased the activity of potassium-active species during the copolymerization of butadiene to more than nine times that of lithium-active species. In this paper, the compositional equation of copolymerization was deduced and the complexity of the apparent reactivity ratio was pointed out Based on our experimental results, the average apparent reactivity ratio of several cases was calculated.
