Thermal diffusivity measurements on three polymer melts were made using the Forced Rayleigh Light Scattering technique. The polymers, which were tested at room temperature where they are in the molten state, included a polydimethylsiloxane and two polyisobutylenes. The optical setup and procedures d
Optical heterodyne scattering measurements are presented for concentrated solutions of unreticulated cis-polybutadicnc as a function of temperature. For a heptane volume fraction v, the second derivative of the free energy with respect to concentration varier approximately as u-z.9 (T-7,). where T,
