摘要
对分子量＞１０５的丙烯酰胺／脂肪醇聚氧乙烯醚丙烯酸酯／甲基丙烯酸钠共聚物的结构与性能之间的关系进行了研究。探讨了共聚物组成、分子量、两亲性支链数和支链长度对共聚物水溶液表面活性及特性粘数的影响，考察了共聚物水溶液在不同温度、ｐＨ值、浓度和时间的物理化学性质及流变行为。研究结果表明：这是一类高分子量、高表面活性、流变剪切稳定、有一定抗盐性的高分子表面活性剂。
he relationship between the structure and properties of acrylamide/alkylpolyoxyethyleneglycol acrylate/sodium methacrylate (AM/AEOnA/NaMAA) tercopolymers with molecular weight ≥1×105 is studied in this paper. The surface activity in aqueous solutions and intrinsic viscosity are researched in detail in relation to the chemical composition, molecular weight, number and length of amphiphilic branch chain in the copolymers and the effects of temperature, mixed salts concentration, pH, and time are also discussed. The rheological behavior of copolymer solutions in water and in brine (containing up to 10% salts) is investigated. It is shown that the surface tension of the copolymers synthesized (1% aqueous solution) is almost independent of the copolymer molecular weight and chemical composition and the oil/water interfacial tension depends upon the coil size of the macromolecules. These are new polymer surfactants of high molecular weight and high surface activity, with good salts tolerancy and shear resistance in aqueous solutions.
