ИСТИНА

By small-angle neutron scattering (SANS) it was shown that solubilization of poly(4-vinylpyridine) in the spherical micelles of potassium oleate results in the formation of complexes with necklace structure, where the mean distance between the micelles bound to polymer (beads) is governed by electrostatic repulsion between them. Direct imaging of complexes was carried out by cryo-translational electron microscopy. Fluorescence spectroscopy, together with SANS evidence, that the polymer penetrates deep into the hydrophobic core of the beads and occupies ca. 60% of their volume. As a result, the average number of surfactant ions in the micelles decreases. The bound charged micelles impart water solubility to the polymer-surfactant system, and, according to dynamic-light scattering of visible light, it behaves like a polymer coil in a thermodynamically good solvent.
