摘要
研究了用丙烯酰胺和丙烯酰氧乙基三甲基氯化铵共聚合成的不同相对分子质量、不同阳离子度的阳离子聚电解质(CPAM)与阴离子型表面活性剂十二烷基硫酸钠(SDS)形成的复合体系的表观黏度和电导率的变化.结果表明,在低于理论等电荷时的m(SDS)/m(CPAM)的范围内,随着SDS加入量增大,复合体系的表观黏度及电导率都表现出先上升后下降的趋势;阳离子聚电解质的阳离子度对与SDS复合体系的电导率影响较大,阳离子聚电解质的相对分子质量对复合体系电导率影响较小.
Cationic polyelectrolytes (CPAM) with different cationic degrees and different molecular weights were prepared by copolymerization of acrylamide and acryloyloxyethy trimethylammonium chloride. Studies on the change of visual viscosity and conductivity were carried out to compound solutions, which were formed by adding an anionic surfactant-sodium dodeclsulfate(SDS) to the solutions of the cationic polyelectrolytes. The results indicate that the visual viscosity and conductivity increase with the addition of SDS in a narrow range, beyond which the visual viscosity and conductivity decrease. And cationic degree of the polyelectrolyte has a more significant effect on such changes than molecular weight.
