摘要： 聚丙烯酰胺(PAM)和部分水解聚丙烯酰胺(HPAM)的特性粘数[η]等物性参数与样品的水解度(DH%)、加盐浓度(Cs)密切相关。在实际应用中,无论油田水、矿山水、洗煤水,一般矿化度都较高,影响PAM和HPAM的使用性能,所以研究DH%、Cs对[η]的影响很有必要。本文在以往工作的基础上研究了[η],Cs,DH%,tgx间的关系,得出了一些有用的结果。

Abstract: Polyacrylamide (PAM) and its hydrolysed product (HPAM) were studied viscosime-trically in aqueous solution of 1, 0.5, 0, 1, 0.025 and 0.01N NaNO3. A linear relationship between tga (see Fig. 1) and degree of hydrolysis (DH%) was found with the same concentration of added salt (Cs) and the same molecular weight of poly-mers. It was also found that the intrinsic viscosity [η] of PAM and HPAM is propor-tional to the C3-1/2. The same [η]∞ values of samples were obtained when the polymer has the same initial molecular weight, but different DH%.
