Low density polyethylene (LDPE) has been studied by dynamic mechanical analysis (DMA) under monoaxial compression. Particular attention was paid to the loss tangent and to dissipation of mechanical energy by internal friction. In this connection it is necessary to take into account the temperature-time conditions of the experiment or introduce appropriate amendments to the results obtained.
