摘要
讨论了双锂引发剂－异戊二烯聚合体系的缔合模型，提出了分子内缔合是双锂引发剂聚合体系的重要特点。并用这种模型分析了造成双锂引发异戊二烯聚合产物相对分子质量分布为双峰并有小分子拖尾现象的原因。
An association model of isoprene polymerization initiated by dilithium initiator was discussed.According to the association model,intramolecular association was important characteristic and was analyzed very well that the bimodal distribution was found during the course of the isoprene polymerization initiated by dilithium in cyclohexane.The experimental phenomenon which the rate of isoprene polymerization initiated by dilithium was slower than by monolithium initiator was explained.
