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
## Abstract An apparatus has been developed for the measurement of thermal conductivity of polymer melts. Based on the transient βline source method,β it is ideally suited to these materials because measurements can be made quickly, before the onset of thermal degradation. Also, little or no sample
