四氢呋喃的阳离子型聚合反应和α-甲基苯乙烯的阴离子型聚合反应都是平衡聚合反应。Tobolsky等已经对平衡聚合反应动力学作了很多研究,认为该反应的产物具有Flory分布。但尚未确定上述分子量分布函数的参变数与哪些因素有关,因此该公式的应用受到限制。近年来,平衡聚合反应的研究蓬勃展开,其反应动力学理论显然也须进一步完善,以便可以通过反应条件来预测,调节和控制反应产物的平均分子量和分散
Both the cationic polymerization of tetrahydrofuran and the anionic polymerization of α-methylstyrene are equilibrium polymerizations. Tobolsky et al. Have made a lot of studies on the equilibrium kinetics of the polymerization reaction, and believe that the product of the reaction has a Flory distribution. However, it has not yet been determined which parameters are related to the above parameters for the molecular weight distribution function. Therefore, the application of this formula is limited. In recent years, research on the equilibrium polymerization has been vigorously carried out, and its reaction kinetics theory obviously needs to be further improved so that the average molecular weight and dispersion of the reaction product can be predicted, regulated and controlled through the reaction conditions
