摘　　要：考察了不同分子量聚乙二醇对十二烷基苯磺酸钠溶液胶束形成（ＣＭＣ）和溶解性（ＫＰ）的影响．结果表明：聚乙二醇使十二烷基苯磺酸钠的ＣＭＣ和ＫＰ降低，在聚乙二醇浓度为０～０．１０ｍｏｌ／Ｌ、分子量为３００～６００范围内，随聚乙二醇浓度增加和分子量增大。The effect of polyethylene glycol on the micelle formation and solubility of sodium dodecylbenzenesulfonate was studied. The results showed that polyethylene glycol reduced the critical micelle concentration (CMC) and Krafft point(KP) of sodium dodecylbenzenesulfonate, and the degree of reduction became bigger with the increment of concentration (0￣0.10 mol/L) and molecular weight(300￣600) of polyethylene glycol.
