ABSTRACT
Changes in polymer viscoelastic properties have been monitored using polymer-coated surface acoustic wave (SAW) devices. Glass transitions induced by temperature changes and absorption of gas phase species have been observed. The changes in wave propagation velocity and attenuation which accompany these transitions are explained using a Maxwell model to describe the viscoelastic properties of the film.
