Abstract

The authors have given results of the investigation into the viscoelastic properties and processes of mechanical relaxation of systems based on polyvinylchloride with a 0-3.0 vol.% content of a nanodisperse-copper powder. The systems were obtained at a frequency of 0.4 MHz at a temperature of 298-353 K. From the Alfrey-Maxwell phenomenological approach, the authors have developedamethod to determine the components of viscoelastic deformation of PVC systems under shear and volume loading. The maximum influence of the filler on the viscoelastic properties of such a system was found in the range of variation in the Cu content 0.05-1.00 vol.%. A quantitative interrelation has been established between the energy-exchange processes in PVC systems and ways have been indicatedI of using them in dynamic mechanical and temperature fields.
