Investigation of the frequency and amplitude dependence of elastomers at temperatures close to the glass-transition region (Tg) could well be a faster and more profitable addition to the wide-spread temperature sweeps used for the determination of mechanical properties of filled and unfilled carbon black rubber systems. The proven sensitivity of the DMTS in the region of Tg is so high that relatively small differences between rubber blends can be detected fast and reliably by such experiments. For such a reason this procedure in combination with the well established temperature sweeps offers interesting experimental setups in the field of quality control. Further experiments are recommended in order to determine the limits of this measuring method as well as the best range of application.
