摘要/Abstract

摘要： 本文用几率与动力学相结合的方法处理二元共聚反应,得到了能够同时表征活性二元共聚物分子量分布与任意长度链段分布的统一分布函数.利用流体力学体积加和性得到了活性二元共聚物的理论GPC谱图计算公式.

Abstract: Polydimcnsional Poisson's distribution function, which can characterize both molecular weight and arbitrary length segment distributions of the binary living copolymers, has been first derived by the method of combining probability with kinetics. It can be transformed into poly-dimensional Gaussian distribution for simplifying calculation. Aformula for calculating the theoretical GPCchromatogram of the product in the living binary copolymerization has also been obtained by using this distribution function and the additivity of hydrodynamic volumes
