摘要：

A surface acoustic wave device was developed to perform thermomechanical analysis of polymer films. Amplitude measurements of Tg for polycarbonate, polysulfone, and single-and two-phase copolymers of the above agree with Rheovibron measurements. Low order transitions (at 24 °C) have been measured in Teflon. Although the Tq measurements using SAW devices were made at 30 MHz, the poor coupling with the surface made by normal disk samples resulted in the excellent agreement observed with classical low frequency methods. On the other hand, cast films, which have good surface contact with the substrate, show the shifts in Tg predicted by the time-temperature principle. © 1979, American Chemical Society.
