Abstract

Abstract: Interaction between three surfactants and hydrophobically associating watersoluble polymers (HAWP) were studied. The experimental results show that the interactions differ according to the types of surfactants. Viscosity increases and interfacial activity decreases for the interaction of alkanolamide or petroleum sulfonate and HAWP, while viscosity decreases and interfacial activity remains consistent for the interaction of betaine and HAWP. With the increase of substituent carbon numbers, interactive force decreases between sulfonates and HAWP, and increases between betaines and HAWP. The force sequence of interaction between surfactants and HAWP is alkanolamide,sulfonate,betaine under the same low substituent carbon numbers. 

摘要： 研究了3种不同类型表面活性剂与疏水缔合聚合物(HAWP)之间的相互作用关系。结果表明,不同类型表面活性剂与HAWP之间表现出较大差异,烷醇酰胺或石油磺酸盐与HAWP相互作用后,黏度增大,界面张力却难以达到较低数值;甜菜碱与HAWP相互作用后,黏度降低,界面活性无影响。磺酸盐与HAWP之间的相互作用随取代基碳数的增加而减小,甜菜碱与HAWP之间的相互作用随取代基碳数的增加而增加。相同低取代基碳数条件下,表面活性剂与HAWP之间相互作用的强弱顺序为:烷醇酰胺>石油磺酸盐>甜菜碱。
