摘要
本文主要论述了两部分内容:一是溶剂极性的经验参数E-T与丁二烯阴离子聚合的某些反应性参数之间的定量关系;二是活性聚丁二烯基锂的官能化,如羟基化、羧基化及卤化反应,并侧重探讨了“假凝胶”的形成原因及其结构模型。
In the third part, the relationship between the reactivity parameters of the anionic polymerization of butadiene and the transition energy ( E ) used as the empirical parameters of solvent polarity, such as the various activation energy of polymerization ( △E ) , coordination energy of Lewis base and active species (△E* ) ,and enthalpy difference of microstructure formation, etc., were studied.Moreover, the functionalization of polybuta-dienyl lithium, such as carboxylation, hydroxylation and halogenation, was also studied, with emphases on the formation of 'pseudo-gel' and the structure modelling.
