摘　　要：合成了以乙二胺为核的 0 5～ 2 5代的半代聚酰胺 胺型树枝状分子 ,对合成的产物进行了碳核磁、红外等表征。采用Wilhelmy吊板法测定了 0 5～ 2 5代不同浓度下半代聚酰胺 胺型树枝状分子水溶液的表面张力 ,探讨了不同代数的半代聚酰胺 胺型树枝状分子的表面活性。结果表明 :半代的聚酰胺 胺型树枝状分子具有一定的表面活性 。A series of EDA core based poly(amidoamine) from 0 5 to 2 5 generation were synthesized and characterized with NMR and IR. Wilhelmy measuring plate method was taken to measure the surface tension of half generation poly(amidoamine) from 0 5 to 2 5 in water solution, and the variety in surface tension of the different generations matching with the variety of concentration were studied. It can be observed in the experiments that the half generations of the poly(amidoamine) show some surface activity in a way which is different from the integrity generations, and the solutions with the same concentration of the different generations have a lower surface tension from generation 0 5 to 2 5.
