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。
In this paper, the polycondensation-cleavage reactions of AB, AA and BB and the AA and BC molecules are discussed. Based on the kinetic equation, the distribution of the polymolecules in these three types of reactions is obtained and several different reaction conditions Under the polycondensation degree p and q is what kind of time function, the use of them and the experimental value of comparison, you can find the polycondensation reaction rate constant K and hydrolysis reaction rate constant k _ (- 1), and AA and BC type molecules In this reaction, the values for K ’and K "can be determined in order to compare the activity of the functional groups B and C. The expressions for the three average molecular weights, their values and their mutual ratios are also discussed, which are only discussed in the absence of hydrolysis The same is true of Flory.
