摘要
采用粘度法研究了纯水及含有NaCl和R_4OH(正丁醇)时,PAM(聚丙烯酰胺)与R_(12)SO_3Na(十二烷基磺酸钠)之间的相互作用。结果表明,在所研究的范围内,PAM与R_(12)SO_3Na胶束之间能形成PAM-R_(12)SO_3Na胶束聚集体。但在纯水和NaCl溶液中,两者之间的作用较弱。若体系中同时存在R_4OH时,作用较强。可能是PAM分子中的—C?与混合胶束中的醇羟基以氢键相结合,形成PAM-胶束聚集体,所以体系的比浓粘度(ηsp/cp)随PAM浓度(cp)的降低而急剧增大,表现出典型的聚电解质性质。
The interaction between polyacrylamide (PAM) and sodium dodecyl sulfonate(R_(12)SO_3Na) in NaCl solution and in NaCl-R_4OH solution have been studied by viscosity measurements. The electro-viscous effect was found, that is, the reduced viscosity of PAM-R_(12)SO_3Na solution increases with the decrease of the concentration ofPAM. These results are interpreted in terms of the formation of polymer-micelleaggregate formed by the binding between the PAM and the R_(12)SO_3Na micelle.
