ABSTRACT

The paper presents the results of studying of a dynamic viscoelasticity of the metalnanodispersible systems obtained on the basis of a polyvinylchloride (PVC) in Megahertz frequency range at the temperatures of 298 K ≤ T ≤ Tg+10 K. From the analysis of peculiarities of energy exchange between the structural elements of the considered composite, the mechanism of emergence of the dynamic viscosity and its interrelation with the Maxwell theory of relaxation viscoelasticity are revealed. The derived analytical relations between the dynamic viscosity, volume and a shear strains allow the prediction of the PVC systems behavior in the mechanical and temperature fields.

KEY WORDS
