| 摘 要： | 用1H NMR自扩散系数，核弛豫和二维NOESY谱研究了新合成苄醚树枝体与丙烯酸杂化嵌段共聚物在水溶液中生成胶团的动态行为.体系中苄醚树枝体与丙烯酸杂化嵌段共聚物的各1H核的自旋-晶格弛豫时间（T1）、自旋-自旋弛豫时间（T2）、自扩散系数和二维NOESY中的交叉峰证明苄醚树枝体与丙烯酸杂化嵌段共聚物在水溶液中形成自聚集，且与不同浓度下聚集体有差别.

| Abstract: | The behavior of a novel amphiphilic block copolymer, Dendr. PE-PAA, in aqueous solution was studied by 1H NMR. The self-diffusion, spin-lattice relaxation time, spin-spin relaxation time and NOESY spectra were obtained. The results suggest that the amphiphilic block copolymer forms self-assembly in aqueous solution, and reveal that the shapes of self-assembly change with different concentration of the solution. |

| Keywords: | Self-diffusion coefficient NMR relaxation Self-aggregate Dender PE-PAA Amphiphilie block copolymer |
