| The paper deals with the results of studying the behavior of a polyvinylchloride (PVC) filled with nanoparticles of copper in the dynamic mechanical fields . The variation of maintenance of highly dispersed metal in the PVC-composite within the range of (0 ... 0.1) vol.% at 293 K≤T≤373 K and frequency (60 ... 200) Hz is shown to cause the nonlinear changes of quasi-elastic shift modulus, logarithmic decrement, effective relaxation time, activation energy of the processes of intra- and intermolecular interaction determined on the basis of interrelation of deformation frequency with the temperature of maximum of the material internal friction. |
