本论文通过大量实验及理论分析,研究了微量水对丁二烯阴离子聚合过程的影响。首次证实了聚丁二烯基锂活性中心和LiOH的失活反应式;首次发现和提出了引发浓度的概念;据此解释了引发和增长过程的有关实验现象及对产物性能的影响;从而给合成工作的设计提供了依据。 In this paper, through a large number of experiments and theoretical analysis, the impact of trace water on the anionic polymerization of butadiene. For the first time, the inactivation reaction of polybutadienyl lithium active sites and LiOH was first confirmed. The concept of priming concentration was first discovered and put forward. Based on this, the experimental phenomena of priming and growth processes and their effects on product properties were explained. The design of synthetic work provided the basis.
