摘　　要：根据作者的大量实验数据和分析文献资料，综合和评述了以路易氏碱的过渡态能来代替它传统的给电子指数、介电常数或永久偶极矩，作为衡量它在阴离子聚合中与活性种作用的强弱标准；此外。This paper dealed with the introduction and review of empirical parameter of solvent polarity of different Lewis bases,used as transition energy(ET) in the anionic polymerization of conjugated diene instead of their donor number(DN),dielectric constant() or permanent dipole moment() for elucidating their coordination reactivity with active centers;besides,some semiquantitative relationships between kinetic or thermodynamic constants of diene polymerization and ET were derived as well.
