Abstract

The resonance method of the shear oscillation of the fixed sample at sound frequencies in a wide range of temperatures measured the real part of the dynamic modulus of elasticity and the tangent of the mechanical loss angle of constructional polyvinyl chloride. It is shown that there is a linear dependence for the amplitudes of the resonant maxima of the sequential modes of oscillations of the samples.
