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.
