Dynamic Mechanical Spectroscopy is a powerful tool for characterizing polymeric materials that, when extend ed over a broad temperature and frequency range, affords valuable structural and morphological information. When applied to polymer blends Dynamic Mechanical Spectroscopy gives further insight to the knowledge of the materials revealing structural and compositional effects. A wide temperature and frequency scanning, hovever, cannot be dove by a single instrument or by a single geometry because of the large variations of viscoelastic properties experienced by polymers as a consequence of temperature and frequency variations. In this paper the results of an investigation on the influence of the two phase structure of polycarbonate SAN blends on dynamic mechanical spectra, performed with three different instruments, are presented.
