Abstract
This study consists of two parts. First, the effect of chain length and structure on the thermal diffusion coefficient D//T is investigated. By examining the retention of a variety of straight-chain and branched polymers in ethylbenzene, D//T is shown to be independent of molecular size and configuration. Second, the roles of polymer and solvent composition are studied. Values of D//T were accordingly obtained for a number of polymer-solvent systems. The results are used to examine several thermal diffusion theories and to correlate D//T with the thermal conductivities and cohesive energy densities of the polymer and solvent.
