The goal of this study is twofold.The first one is to assess the applicability of approaches based on dynamicmechanical 6 Pc. Sectional analysis to investigate the viscoelastic properties of a self-adhesive synthetic rubber.The second goal is to identify the parameters of a viscoelastic model which accurately represents the frequency-dependent mechanical properties.For that purpose, the time-temperature superposition principle is successfully applied to build the master curves of the material up to 1 MHz.

The thickness of the samples and the thermal expansion effects are found to have a negligible influence on the mechanical properties measured by dynamic-mechanical analysis.The parameters of a generalized Maxwell model and a fractional derivative model are identified from the obtained master curves and lead Rattles to an accurate representation of the frequency-dependent mechanical properties of the rubber.
