Summary Hydrodynamic radii, R H D and R H η , determined, respectively, from — translational diffusion coefficients and intrinsic viscosities are compared with radii of gyration SZ for polystyrene of narrow molecular weight distribution in good-solvent systems, ethylbenzene and tetrahydrofuran. The SZ data indicate THF is of comparable solvating power to ethylbenzene which, in turn, based on literature data is similar to benzene in its affinity for polystyrene. The ratios ϱ1 = Sz/R H D and ϱ2=R H η /R H D are much larger for polystyrene in ethylbenzene than in tetrahyaroruran. These results are interpreted to indicate the presence of a large draining effect in the ethylbenzene system.
