The zwitterionic monomer, 1-(2-hydroxypropyl-sulfo)-acrylamide ethyl-N,N-dimethyl ammonium chloride (MeSA) was copolymerised with acrylamide (AM), acrylic acid (AA), and a hydrophobic monomer N,N-diallyl oleamide (DNDA) to obtain the zwitterionic hydrophobic association polymer AM/AA/DNDA/MeSA. The structure of the hydrophobic association polymer was characterised by ¹H NMR, FT-IR, and intrinsic viscosity studies. The self-assembly system of the polymer and the surfactant Tween-40 was then formed, and the rheological properties and adsorptive performance of the self-assembly system were investigated. The result showed that the polymer–surfactant self-assembly system had good properties such as thickening, temperature resistance, salt resistance, and shear resistance. It is shown that the thermal thickening phenomenon, which allows the system to be used as a good petrochemical product in a high-temperature environment, provides a vital research foundation for the future application of this kind of self-assembly system.

将两性离子单体1-（2-羟丙基-磺基）丙烯酰胺乙基-N，N-二甲基氯化铵（MeSA）与丙烯酰胺（AM），丙烯酸（AA）和疏水性单体N，N-二烯丙基共聚合用油酰胺（DNDA）获得两性离子疏水缔合聚合物AM / AA / DNDA / MeSA。疏水缔合聚合物的结构特征为¹1 H NMR，FT-IR和特性粘度研究。然后形成了聚合物和表面活性剂Tween-40的自组装体系，并研究了该自组装体系的流变性能和吸附性能。结果表明，聚合物-表面活性剂自组装体系具有良好的性能，如增稠，耐温，耐盐和抗剪切性。结果表明，热增稠现象使该系统可以在高温环境下用作良好的石油化工产品，为此类自组装系统的未来应用提供了重要的研究基础。
