The method, established by Price et al. to observe the polymer micelle, was modified and applied to the region of high polymer concentration. The novelty of our method consists of the preparative method of the specimen for transmission electron microscopy. Polymer solution was diluted and solvent was evaporated rapidly before the micelle was decomposed. As a result, dilution ratio had no effect on the decomposition of polymer micelle, and the original micelle structure was conserved over 10 wt % block copolymer solution if the operations were carried out within 30 min. This time limit related to the concentration of solution.
