Abstract:

A resonant method for the determination of the dynamic properties of solid polymers is presented. A composite oscillator driven by a piezoelectric crystal, in longitudinal oscillations and at a frequency of the order of 50 kHz, is employed. The changes in the storage and loss moduli, the loss tangent and the attenuation coefficient for the material, as a function of temperature, can be obtained from the changes in the resonant frequency, the width of the resonance peak and the transference function of the composite oscillator. Finally, some data obtained in specimens of vulcanized rubber are presented, to illustrate the applicability of the method. © 1992.
