| Popis: | The application of EPR spin probe and spin label technique for solving the two problems of polymer physical chemistry is considered. The first problem is the determination of conformational state and chain sizes in amorphous solid polymers. This determination is based on the analysis of the intramolecular dipolar broadening of EPR spectra of spin labelled macromolecules in glassy solvents or in the bulk of unlabeled polymers at 77 K. The second problem is the determination of molecular mobility and structure of two polymer colloid systems: (a) the complex of colloidal silica and synthetic polycation macromolecule and (b) polymer-surfactant micellar organized systme. |
