| 摘 要： | 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．

| Abstract: | Monte Carlo method for studying the molecular weight distribution (MWD)and the kinetics of polymerization has been developed in this paper. This methodallows for simulation of the kinetics of polymerization and the evolution of MWDsimultaneously. By using this method for the AB--AA type condensationpolymerisation of unequal functional group reactivity, the simulation results agreewith the experimental results quite well. The results reveal that the AA monomerwith high funCtional group reactivity can promote the reaction and narrow theMWD of the products. Therefore, a practical method for accelerating the condensation polymerization and modifying the MWD of polyphenyl ether sulfone hasbeen suggested. |
