| 520 | 3 | |a The sizes and local mobility of nano-sized aggregates formed in aqueous solutions of polydiphenylenesulfophthalide before and after its treatment with alkali metal hydroxides were determined by the method of electron paramagnetic resonance (EPR) spectroscopy and the method of dynamic light scattering. Nano-aggregates possess a dense hydrophobic core whose local mobility is commensurable with the local mobility of solid polystyrene. The solubility of these aggregates is explained by the presence of hydrophilic groups (lyophilizing corona) in their outer layer. The hydrophobic core of nano-aggregates is not uniform; it contains a significant amount of less ordered ("defect”) regions. This is confirmed by the superposition of EPR spectra of spin probes. Dense non-uniform structures of aggregates are formed in diluted solutions and maintain their integrity during gel formation as the concentration of solution increases. | |
