Abstract

An apparatus is described which allows one to study the mutual effect of stress-relaxation processes occurring for various deformations and vibrations of sound frequency. The effect of mechanical stress and stress relaxation is investigated for mechanical dynamical properties in samples of high-pressure polyethylene, isotactic polypropylene, polyamidoester on a base of anilinophthalein, and polyimide obtained by the solid-phase ring formation of polyamidoester. The effect of the supermolecular structure of polypropylene on the nature of the temperature dependence of the loss angle tangent is shown.
