摘　　要：以二甲基十八烷基(3-丙烯酰胺丙基)溴化铵(DMOAB)和丙烯酰胺(AM)为单体,十八烷基三甲基氯化铵(OTAC)为混合胶束剂,采用自由基胶束共聚法制备了兼具离子性和疏水缔合两种结构特性的疏水缔合聚丙烯酰胺P(DMOAB-AM),其结构经FT-IR表征。运用表观粘度法初步研究了表面活性剂对P(DMOAB-AM)溶液表观粘度的影响。结果表明:油酸钾(KOA)对P(DMOAB-AM)溶液表观粘度的影响明显优越于OTAC。KOA与P(DMOAB-AM)之间存在协同增粘效应,且P(DMOAB-AM)/阴离子表面活性剂缔合体系"网络结构"的强弱取决于表面活性剂烷基链的长度。A hydrophobically associative polyacrylamide named as P（DMOAB-AM） with two structural characteristics of ionic and hydrophobic association was prepared via free-radical micelle copolymerization using dimethyl octadecylalkyl （3-acrylamidopropyl） ammonium bromide（DMOAB） and acrylamide（AM） as monomers and octadecyl trimethyl ammonium chloride（OTAC） as mixed micelles agent. The structure was characterized by FT-IR. The effect of surfactants on the apparent viscosity（ η a ） of P（DMOAB-AM） solutions was preliminarily studied using apparent viscosity method. The results showed that the effect of potassium oleate（KOA） on η a was stronger than that of OTAC. There exists synergistic viscosity enhancement between P（DMOAB-AM） and KOA in the associative system. Besides, the strength of “network structure” formed by P（DMOAB-AM） and surfactant depends on the length of the alkyl chain of the surfactant.
