凝胶点官能度是重均官能度,还是数均官能度

The Gel Point Functionality: Whether Wt. Av. Functionality or No, Av. Functionality

Flory和Stockmayer等的凝胶化理论用重均官能度表示凝胶点或凝胶生成的临界条件,虽已有50多年的历史,并为各国学者所公认,但从分析凝胶点定义的物理意义出发,只要用简单的数学分析,即可证明用重均官能度而不用数均官能度表示凝胶点,与反应程度定义的物理意义和Flory的两个基本假设不符。凝胶化理论新概念用数均官能度表示凝胶点,则不存在不符的问题。

The gel point or the critical condition of gel formation in Flory' s and stockmayer' s gelation theories has been expressed as weight average functionality for more than fifty years and this has been recognized by scholars at home and abroad .But from the analysis of the physical meaning of the definition of gel point, it can be easily proven that the gel point, expressed as weight average functionality, not as number average functionality, is not conformed to the physical meaning of the definition of reaction extent and Fiory' s two basic assumptions,The new concept of the gelation theory that the gel point is expressed as number average functionality does not present the problem.
