| 摘 要： | 运用概率统计的方法推导了调节剂与缩聚物相对分子质量及相对分子质量分布的关系式。用已内酰胺开环缩聚反应进行了实验验证。指出:调节剂的官能度对相对分子质量分布有较大的影响。聚合物的特性粘度不仅是相对分子质量的函数,也是相对分子质量分布的函数,并得出了聚酰胺-6特性粘度与数均相对分子质量及相对分子质量分布指数的经验关系式。

| Abstract: | The relationships expressing the relative molecular mass distribution of polymers affected by regulators were theoretically derived by the method of mathematical statistics. It is found that the presence of regulators affects the equilibrium value of polydispersity index of polymers. In addition, it is demonstrated that the intrinsic viscosity of polymer is related not only to average relative molecular mass but also to relative molecular mass distribution. In this paper, the authors have tried to come up with an experimental equation which correlates the relative molecular mass with intrinsic viscosity of polyamide 6 with bifunctional regulators. |
