| Abstract: | Using low-frequency Raman spectroscopy, the structure of aqueous solutions of polyacrylic acid as a function of polyelectrolyte concentration and chain length was studied. The fractal dimension of structures in aqueous solutions of polyacrylic acid with different acid concentrations and polyion chain lengths was determined. The size of fractal regions in systems with different structures was estimated. |
