本文討論AB型,AA和BB型以及AA和BC型分子间的缩聚-裂解反應,由動力学方程出發,得到这三种类型反應过程中高聚分子的分佈情况,并求得几种不同反應條件下的缩聚度p和q是何种時间的函数,利用它们和实验数值比較,可以求得縮聚反應速度常数K和水解反應速度常数k-1,并在AA和BC型分子间的反應中,可以求得K'和K"的此值,藉以比较官能團B和C的活潑度.还討論了三种平均分子量的表示式、数值以及它们相互的比值,後者僅在没有水解作用的情况下,才和Flory的结果相同.

A more general mathematical analysis of the kinetics of polycondensation-depolycoudensation reactions is Riven in the article.Three different types of reactions are considered, namely, (1) reactions between molecules AB and AB, (2) reactions between molecules AA and BB, (3) reactions between molecules AA and BC.One of the condensation products is assumed(without loss of generality) to be water.
