摘要

本文用电子显微镜深入的研完了部分水解聚丙烯酰胺在水溶液中的形态。给出大分子的伸展网状结构是其稀溶液高粘度的结构本质。并详细讨论了聚合物的水解度、分子量、外加盐种类及波度与分子聚集状态的关系。

Abstract

Partial hydrolyzed polyacrylamide (HPAM) is a polyelectrolyte. Due to the electrostatic repulsion of intramolecular -COO- groups

the polyacrylamide molecules in water are extended to form filamentous structure

and its aqueous solution has very high intrinsic viscosity.This paper presents a detailed study on the relationship between structure and viscosity of solution. The influences of hydrolysis degree of PAM molecular weight of HPAM and salt concentration on the morphology have been discussed.
