| 摘 要： | 采用反相乳液聚合法，以丙烯酰胺（AM）、2-丙烯酰胺基-2-甲基丙磺酸（AMPS）、十八烷基二甲基烯丙基氯化铰（MJ-18）为原料，合成了疏水缔合AM／AMPS／MJ-18三元共聚物，考察了反应条件对乳液稳定性、单体转化率、共聚物特性粘数及抗盐性的影响。确定了最佳合成条件：反应温度25℃，过硫酸铵／亚硫酸氢钠引发剂加量（以水相质量计）0．15％，Span-80／Tween-80复配乳化剂加量（以油相质量计）6％，油水体积比1：1，体系pH值7～9，单体总加量（以水相质量计）50％，其中疏水单体MJ-18含量0．6％。

| Abstract: | A hydrophobically associating AM/AMPS/MJ - 18 terpolymer was synthesized by inverse emulsion polymerization using acrylamide（AM）, 2 - acrylamido - 2 - methylpropanesulfonic acid （ AMPS）, octadecyl dimethyl allyl ammonium chloride （MJ - 18 ） as raw materials. The effects of reaction conditions on the emulsion stability, monomer conversion, intrinsic viscosity, and saltresistance were investigated. The optimum synthetic condition was determined as follows： reaction temperature was 25℃, ammonium persulfate/sodium bisulfite initiator was 0. 15% （based on aq. phase mass）, Span -80/Tween -80 compound emulsifier was 6% （based on oil phase mass）, oil/water ratio was 1 ： 1 （v/v）, the pH of system was 7 -9, total addition amount of the monomers was 50% （ based on aq. phase mass）, and MJ - 18 content was 0.6%. |
