| 摘 要： | 讨论了含引发机制的Af-Ag型缩聚反应体系,根据该反应体系的数量分布函数,导出凝胶点附近分布函数和高分子矩的渐进表示式,进一步应用标度变换,得到了描述溶胶-凝胶相变的广义标度律,揭示出含引发机制的Af-Ag型缩聚反应体系的固化过程是一个相变过程。

| Abstract: | By means of the equilibrium number fraction distribution for type polycondensation involving initiation mechanism, the asymptotic distribution and polymer moments near the gel point are deduced. As a direct result of scaling transformation, a generalized scaling law which characterizes the sol-gel transition is obtained. |
