Results of investigation of behaviour of the polyvinylchloride (PVC) filled with nanoparticles of copper in dynamic mechanical fields are presented. As shown, at change of content of highly dispersed metal in a range of 0–0.10 vol.% in PVC-composite at 293 K???T???373 K and frequencies of 60–200 s?1, such phenomena take place as nonlinear changes of quasi-elastic shift modulus, logarithmic decrement, effective time of a relaxation, energy of activation of intra - and intermolecular interaction, which is determined on the basis of interrelation between the frequency of deformation and the temperature of maximum of internal friction of material.
