| Popis: | The pulse NMR method in a wide temperature range has been employed to investigate the processes of molecular mobility in the polydialkoxyphosphazane series with a variable length of the side alkyl chain. The NMR characteristics have been determined and the observed temperature transitions identified. The structure of the main inorganic chain was found to influence the character of the motion of the terminal methyl groups of the polydialkoxyphosphazenes. It is shown that the main features of molecular motion in them are determined by the weak dependence of the motions of the side and main chains thanks to the raised flexibility of the latter. |
