摘要: 高聚物与表面活性剂的相互作用已有许多研究,其中的高聚物有聚氧乙烯、聚乙烯吡咯烷酮、聚乙烯醇、甲基纤维素以及蛋白质等。Sabbadin主要研究了部分水解聚丙烯酰胺。本工作考察非水解的聚丙烯酰胺(PAM,大连同德化工厂产品)对十二烷基硫酸钠(SDS)增溶二甲基黄(DMAB)的影响。

Abstract: The interaction between polyacrylamide (PAM) and sodium dodecyl sulfate (SDS) has been studied in terms of the solubilization of dimethylaminoazobenzene (DMAB). The solubilizing power of SDS becomes greater with the addition of PAM, the extent depending on the molecular weight. The amount of solubilized DMAB increases with the raising temperture. On adding NaCl in SDS solution, the solubilization ability increases, but in SDS-PAM solution, decreases. Thus it is deduced that DMAB taking neutral form solubilizes in the core of micelle in SDS solution and taking acidic form solubilizes on the palisade of micelle in SDS-PAM solution.
