The analysis of relaxation parameters changing during their measurement

Abstract

It is shown that at research of such relaxation characteristics as the tangent of angle of mechanical losses, dissipation of mechanical energy as a result of the internal friction measured at periodic action of monoaxial pressure of compression on the sample of a polymer (LDPE) in the high-elasticity state, development of relaxation processes occurs in the sample. In this connection it is necessary to consider the temperature-time conditions of the experiment.
