含引发机制的A_f-A_g型缩聚反应Z-均回转半径研究

Z-averace radius of gyration for the A_f-A_g type polycondensation involving initiation mechanism

讨论了含引发机制的Af-Ag 型缩聚反应体系Z -均回转半径 .利用枝状高分子成键的统计分析 ,给出组合因子分解公式 ,并得到均方回转半径的表达式 ;进一步结合数量分布函数 ,定义k次高分子半径 ,并给出计算k次高分子回转半径的循环公式 ,最后得到凝胶点前Z

By means of statistical theory, the formula of combined factor C mln and the mean square radius of gyration for the A f -A g type polycondensation involving initiation mechanism were obtained. And by means of the number fraction distribution, the k -th polymer radius is defined to give a recursion formula of the radius of gyration for pre-gel. Furthermore, the 2nd radius of gyration and the Z-average radius of gyration are obtained explicitly.
