The self-assemble behavior of amphiphilic poly(styrene-b-acrylic acid), P(S-b-AA), in selective solvents was studied by dynamic light scattering(DLS). The diameters of micellae were found to be decreased and then increased with the increase in the concentration of the calcium ion in solvent. The average diameter of micellae was minimum when the concentration of the CaCl₂ was 0.2 g/L. In addition, the distribution of micellae became narrow with the increase in the ethylenediamine concentration.
