摘　　要：以三乙烯四胺、环氧氯丙烷、叔胺为原料,无水乙醇作为反应溶剂,设计合成了一系列新型的多聚阳离子表面活性剂,对其结构进行了表征,考察了其水溶液的表面活性和界面性能及疏水碳链长度对性能的影响。结果表明:此类表面活性剂具有非常好的表界性能,最低表面和界面张力分别达到了27.6mN/m和0.004 5mN/m。A series of novel oligomeric cationic surfactants were designed and synthesized from triethylene tetramine, epoxy chloropropane and tertiary amines with absolute ethyl alcohol as reaction solvent. Compounds were verified by IR and 1 H NMR. Surface and interracial activities of surfactants in the aqueous solution have been studied. The effects of the carbon numbers in their hydrophobic chains on properties were analyzed. Results show that oligomeric surfactants posses high surface and interfacial activity. The minimum surface tension and interfacial tension are 27.6 mN/m and 0. 004 5 mN/m, respectively.
