The dielectric relaxation processes in poly(azourethaneurea) prepared from diphenylmethane-4,4′-diisocyanate (MDI) and poly(ethylene adipate) glycol were studied in the range 200-390 K using thermally stimulated depolarization currents (TSDC). The TSDC spectra obtained on original sample, annealed sample, and both annealed and stretched sample showed significant differences which were explained in terms of the supramolecular structure of polymers. It was accepted that the polymers have a multiphase supramolecular structure. [ABSTRACT FROM AUTHOR] |
