| 摘 要： | 本文利用环氧丙烷开环聚合的基本理论，推导出表征环氧丙烷链转移常数Ｃ＿Ｍ与平均聚合度的关联式，据此提出了较简便可行的测试Ｃ＿Ｍ值的方法，并与作者曾提出的环氧丙烷链转移常数的经验式：Ｃ＿Ｍ＝１４６２·ｅｘｐ（—３９９１．１／Ｔ）的计算值进行了比较分析，进而指出了该实验测定值的精确程度。

| Abstract: | The basic theory of the opening polymerization of propylene oxide is used to deduce a relationship between the chain transfer constant of propylene oxide C_M and the average polymerization degree by wich a simple method for the determination of C_M is found. The experimental results were compared with the empirical formula suggested by the author C_M=1462exp( 3991.1/T), and the accuracy of the experimental value is assessed. |
