By using the methods of wide- and small-angle x-ray scattering, the structures of two types of polyelectrolyte complexes based on Na-salt carboxymethylcellulose or Na-salt of polymethacrylic acid and hydrochloride are investigated. It is shown that, in a volume of polyelectrolyte complexes based on Na-salt carboxymethylcellulose, a layered quasicrystalline structure is formed, whereas the polymer systems based on Na-salt of polymethacrylic acid have predominantly an amorphous structure similar to that of the initial anionic polyelectrolyte.
