N2 - A simple scaling relation was proposed to predict the effects of molecular weight and flow rate on the stress-induced migration of polymer molecules subjected to simple shear flow. The predicted results were compared with experimental measurements in thermal field-flow fractionation (ThFFF). Retentions were measured for linear polystyrene samples with molecular weight up to thirty million. The experimental results were consistent qualitatively with the predictions.
