| 摘 要： | 采用ＭｏｎｔｅＣａｒｌｏ方法模拟了不等活性的ＡＡ－ＢＢ型缩聚反应的数均分子量随时间演化的动力学行，并在模拟中首次考虑了逆反应，模拟结果与实验结果吻合得很好，从而合理地解释了聚芳醚腈砜合成反应的动力学曲线在反应初蓁后期偏离线性关系的原因。

| Abstract: | Monte Carlo method for studying the kinetics of AA-BB type condensation polymerization of unequal functional group reactivity is presented in this paper. By using this method we simulate the evolution of M n of the synthetic reaction of poly(arylene ether intrile sulfone)s (PENS), and for the first time introduce the reverse reaction into the simulation. The results obtained from the simulation are in good agreement with the experimental results, so that we explain feasonably why the kinetics curve slide from line rule in the original and final stage of the synthetic reaction. |
