Sedimentation coefficients are reported for three polystyrene fractions (molecular weights 1.1 × 105, 3.9 × 105and 1.8 × 106) in toluene andtrans-decalin (θ-conditions) up to high concentrations. The difference between the sedimentation behaviour in good and poor solvents is discussed; an “anomalous” effect was observed in toluene in a concentration region where incipient entanglement is likely.
