单官能团分子在缩聚反应中对分子量及其分布的影响

The Effect of Monofunctional Molecule on Molecular Weight and Its Distribution in Polycondensation Reaction

本文建立了单官能团分子对A-B 型、A-A、B-B 型二类线型缩聚反应产物的分子量分布影响的偏微分方程,并用Laplace 变换法求解,得到此二类缩聚反应类型的分子量分布.文中还详细讨论了缩聚反应产物中端基结构不同的分子的分子量分布.

A general differential equation for the effect of monofunctional mole-cule on molecular weight distribution of two types of A-B and A-A B-B linearcondensation polymer was deduced and the molecular weight distribution of thesetwo types of condensation polymer was obtained by Laplace transform.Forther-more,the molecular weight distribution of polymer with different endgroup inabove condensation reaction was also discussed in detail.
