摘　　要：以丙烯酸十二酯(LA),2-丙烯酰胺基十六烷磺酸(AMC 16 S)与α-甲基苯乙烯(BM)为单体,采用溶液聚合法制备了新型油溶性稠油降粘剂AMS,其结构经红外和热重表征。并研究了其稠油降粘性能。当AMS最佳加量为4000 mg/L时降粘率为56.94%。探讨降粘机理可知AMS中的酰胺基、酯基、磺酸基和苯环破坏了胶质和沥青质形成的片状堆积结构,从而降低了稠油的粘度。A new type of oil-soluble heavy oil viscosity reducer was prepared using dodecyl acrylate(LA),2-acrylamidohexadecanesulfonic acid(AMC 16 S)andα-methylstyrene(BM)as monomers by solution polymerization(AMS).The polymer was characterized by FT-IR and TG.When the optimal AMS dosage was 4000 mg/L,the viscosity reduction rate was 56.94%.It is known from the discussion of the mechanism of viscosity reduction that the amide group,ester group,sulfonic acid group and benzene ring in AMS destroy the flake-like stacked structure formed by gum and asphaltene,thereby reducing the viscosity of heavy oil.
