推导了异戊二烯在环已烷-二氧六环混合溶剂中的负离子聚合机理，并通过实验进行了验证。研究表明，丁二烯聚合机理原则上同样适用于异戊二烯的负离子聚合。推导出非1,4-结构产物含量与极性添加荆用量的关系式为1g[(a-b)/(xv-b)-1]=nlg[PA]+1gk1，求得了a,b,n,K1与温度的关系式，并指明了各自的物理意义。

The mechanism of anionic polymerization of isoprene with cyclohexane and dioxane as solvent was studied and improved by experiment.The experimental results showed that the mechanism of anionic polymerization of butadiene was also fit for the anionic polymerization of isoprene. The relationship between mole fraction of non - 1, 4 - unit and
the concentration of dioxane was deduced as follows:
lg[(a- b)/(x,- b) -11 = alg[PA] +lgK′The physical meanings of a, b, n, and K′ were pointed out and the formulas of relationship between them and the temperature were obtained.
