Dynamic measurements (sedimentation, viscosity, size exclusion chromatography) were carried out on a series of polystyrene samples dissolved in a good solvent, tetrahydrofuran. Using the Weill-des Cloizeaux theory we show that it is possible, from these data, to study how the coil radius of gyration varies with molecular weight. The validity of the thermal-blob model is confirmed by our results, and the expected power laws under and above the cross-over domain are indeed observed. In size-exclusion chromatography, we observe that several calibration curves may be obtained from the experimental data.Nous avons mesuré certains paramètres de transport (sédimentation, viscosité, chromatographie d'exclusion stérique) pour une série de polystyrèn...
