摘　　要：在考察单一阳离子双子表面活性剂、阳离子聚合物溶液粘度的基础上,详细研究了阳离子聚合物对双子表面活性剂溶液的增粘作用及两者形成复合体系后粘度的影响因素。结果表明,阳离子双子表面活性剂Cn-s-n.2Br-1溶液粘度随其浓度增加而逐渐增大,当其连接基s=2时,随烷基链碳数m增大,其对溶液增粘性增大;向其溶液中添加适量阳离子聚合物,可使活性剂溶液粘度增大,但两者间无明显增粘协同作用。温度、pH值均使阳离子双子表面活性剂/阳离子聚合物复合体系粘度先增后降;而剪切速率增大、剪切时间延长及NaCl/NaSal(水杨酸钠)加量的增加均使复合体系粘度明显下降;就NaCl与Na-Sal影响程度而言,NaSal影响更明显。On the basis of investigating single cation Gemini surfactant and cation polymer solution viscosity,viscosifying action of cation polymer on Gemini surfactant solution and influential factor on the viscosity of cation polymer/Gemini surfactant compound solution were studied.The results show that viscosity of the cation Gemini surfactant solution increases with its concentration increase and alkyl chain length is equal to(spacer s=2),its viscosity increases with raising of cation polymer,but there is no obvious viscosifying effect between polymer and Gemini surfactant.The viscosity of cation Gemini surfactant/cation polymer compound system.increases first and then falls down induced by temperature and pH value its viscosity decreases obviously with the increase of shear rate,shear time and NaCl/NaSal dosage.For the influence of NaCl and NaSal,the influence of NaSal is more obvious
