Abstract
The effect of ionizing irradiation on dissipative processes of α-, β-, and μ- relaxation in a polymer either filled or unfilled with highly dispersive iron powder considering the polymer structure has been investigated via the method of dynamic mechanical relaxation spectroscopy. The polymer structure has been analyzed on the basis of surface topography data obtained via atomic force microscopy. A correlation between the effect of irradiation on the temperature position of the maxima and the intensity of dissipative processes on the internal friction spectra, as well as on the temperature-frequency dependence with structural changes that have developed in cross linking and compaction of the polymer, have been demonstrated.
