摘要

在二元链式共聚反应中，竞聚率r

，r

可以在很大范围内变化，相应F

-f

关系曲线也有多种类型。教科书中常常首先按照r

与r

的乘积(r

•r

)与1的大小关系比较进行分类，这样的分类法缺乏直观性，对初学者而言较难理解。本文直接按照r

与r

本身数值的大小提供一种更加基础的分类法，并按照相应体系分类讨论，以期对共聚反应的教学以及相关研究起到参考作用。

Abstract

In copolymerization reaction of two monomers

reactivity ratios r

and r

may vary in a wide range. Thus

correspondingto the different values

there are diverse kinds of the F

—f

curves. In most textbooks

the first step of the classification process is to compare the product of r

and r

• r

) with the value 1. However

this indirect classification method might be opaque to some beginners. This article will provide a novel and fundamental strategy directly based on r

and r

value per se

followed by the discussion of diverse systems. We hope the classification could be helpful to polymer chemistry education as well as the frontier research.
