摘　　要：实验室合成了两个系列丙烯酰胺 烷基聚氧乙烯醚丙烯酸酯类两亲疏水缔合聚合物 ,考察了不同盐 (NaCl)浓度下 ,此类聚合物的特性粘数与链刚性参数的变化规律以及聚合物中疏水基团类型。Two series amphipathic hydrophobically associating polymers are used in this study: acrylamide/acrylic acid/nonylphenylene polythylene ether acrylate (AP series) or dodecyl polyethylene ether acrylate (AD series) copolymers with PAM as control. [η] values are determined at 30℃ in aqueous NaCl solutions of different concentration as well as in distilled water. Following parameters are found and discussed for these polymers: Huggins′ constant K H; parameter S as the slope of [η] I -0.05 linear plot; chain stiffness B determined using Smidsrod Haug equation.
