✦ Synopsis

The temperature dependence of acoustic shear velocities are reported for Poly-Penco nylon, type G Plexiglass [poly(methyl methacrylate], TFE Teflon (tetrafluoroethylene), low-and high-density polyethylene, Lexan (polycarbonate), and Delrin Acetal (nylon). Most of the data were obtained at a frequency of 1 Mc./sec. over the temperature range of 25-100°C. In addition, previously unreported longitudinal velocities to -125'C. are reported for Lexan and Delrin Acetal.
