综述了６０～８０年代有关聚丙烯酰胺水溶液贮存过程中粘度稳定性研究的发展状况，重点介绍了解缠和断裂观点及分子内氢键破坏理论，并提出了稳定ＰＡＭ溶液粘度的几种可能途径。
In this paper, the development of the study on the viscosity stability during the storage of polyacrylamide aqueous solution from 1960s to 1980s is reviewed. The theories of entanglement and fracture and the theory of intramolecular hydrogen bond failure are introduced emphatically. Several possible approaches to stabilize the viscosity of PAM solution are also proposed.
