| 摘 要： | 在二氧化碳与环氧丙烷的共聚反应中，加入某些调节剂可以得到所需要分子量和官能度的共聚物。这是因为在活泼氢和催化剂活性中心之间有链转移反应发生。我们提出了共聚反应的机理并导出了相应的共聚反应速度方程式，这一机理和速度方程式与实验相符。

| Abstract: | In the copolymerization of CO 2 and propylene oxide, copolymers with designed molecular weight and OH functionality can be obtained by the addition of certain regulators. This is due to the chain transfer reaction between the acti ve hydrogen and the active centers of the catalyst. Mechanism for this copolymerization was suggested and accordingly a rate equation was deduced, which was consistent with the experimental observations. |
