Results of the realized DMA tests in the form of temperature dependence of average storage modulus E′(T, f ), loss modulus E”(T, f ) and loss tangent tanδ(T, f ) in a temperature range T from 146 K up to 527 K at external dynamic mechanical load frequencies f = 0.5, 1, 2, 5 a 10 Hz and a constant strain rate of 0.1 Hz are shown in Figure 2.
