| 摘 要： | 1H NMR谱和二维核Overhauser效应谱(2D NOESY)研究结果表明新型疏水缔合丙烯酰胺/2-苯氧乙基丙烯酸酯无规共聚物(PAM/POEA)在水溶液中的自聚集主要发生在酚基间以及酚基与主链的相互作用上，在PAM/POEA自聚集体中酚基主要位于丙烯酰胺主链骨架附近.

| Abstract: | ~1H NMR spectroscopy with two-dimensional nuclear Overhauser enhancement (2D NOESY) measurements was used to study the aggregation behavior of a novel hydrophobically associating copolymer composed mainly of acrylamide (AM) and a small amount of 2-phenoxyethyl acrylate (POEA). The results show that aggregation of the copolymer PAM/POEA mainly derives from the interactions among the phenoxy groups and that between the phenoxy group and the acrylamide backbone. 2D NOESY experiments unambiguously show that, in the POEA/PAM aggregates, the phenoxy groups of the hydrophobic parts of POEA are possibly located in the vicinity of the acrylamide backbones. |
