摘　　要：以丙烯酰胺(AM),疏水单体十八烷基二甲基烯丙基氯化铵(MJ_(18))为单体,N,N-亚甲基双丙烯酰胺(DMAM)为交联剂,过硫酸铵-亚硫酸钠氧化还原体系为引发剂,采用水溶液聚合方法,合成了疏水型水膨体 AM/MJ_(18)共聚物。根据正交试验,确定了最佳合成条件:反应温度为60℃,疏水单体 MJ_(18)含量为0.5%,引发剂用量0.45%,交联剂用量0.04%。在此条件下合成的水膨体具有较好的耐温抗盐性和热稳定性,是一种适合油田深部调剖作业用的水膨体颗粒。A hydrophobic swellable AM/MJls copolymer was synthesized by aqueous solution polymerization, using acryl amide and MJls as the main monomers,DMAM as cross- linking agent, and （NH）4S2O8 - Na2S2O3 as initiating agents. The copolymerization condition was optimized by orthogonal test as follows ： reaction temperature 60 ℃, monomer MJls 0.5 %, initiating agent 0.45 %, and cross - linking agent 0.04% . The synthesized copolymer had good heat and salt resistance and thermal stability. It was suitable for in- depth profile modification.
