将缩聚产物分子量分布（ＭＷＤ）的ＭｏｎｔｅＣａｒｌｏ方法和聚合反应动力学的ＭｏｎｔｅＣａｒｌｏ方法结合起来，可在研究聚合反应动力学的同时获得ＭＷＤ随时间的变化．将该方法用于研究非等活性的ＡＢ—ＡＡ型缩聚反应的动力学与实验结果十分一致．通过考察高活性ＡＡ单体加入后对其动力学行为和相应的ＭＷＤ的影响，作者提出了对聚苯撑醚砜的ＡＢ型缩聚合成中加快其反应速度和改进ＭＷＤ的实用方法．
Combining the Monte Carlo method of MWD and the Monte Carlo method of polymerization kinetics, the MWD over time can be obtained while studying the polymerization kinetics. The kinetics of this method for studying the non-isomeric AB-AA polycondensation reaction is in good agreement with the experimental results. By investigating the influence of high activity AA monomer on the kinetic behavior and the corresponding MWD, the authors proposed a practical method for accelerating the reaction and improving the MWD of polyphenylene ether sulfone in AB type polycondensation.
