摘要
以 ABg型超支化高分子反应为例 ,对该反应体系的反应动力学和统计力学进行了研究 ,并探讨了二者之间的关系 .进一步给出反应体系的反应程度与体系的 Gibbs自由能等热力学量间的解析表达式以及反应程度与浓度和时间等物理量之间的关系 .
We have theoretically investigated the statistical mechanics and dynamics of the hyperbranched polymerization of AB g type, a relationship between the conversions of the two species and the Gibbs free energy is obtained, which makes the characterization of the polymer physical quantities can be simplified. Furthermore, the relationship between the dynamics and statistical mechanics of the system under study is pointed out, and then the conversions of the two species as a function of time is derived. Based on the results obtained in this paper, the hyperbranched polymerization can be investigated in a deeper level.
