Intrinsic viscosity measurements were carried out on dextran samples (of different molecular weights) in aqueous solutions at 25, 28, 31, 34, 37, 40, and 43Β°C. The extrapolation methods were used for the data; they gave unperturbed dimensions, K 0 , of the chain. The unperturbed root-mean-square end

β¦ Synopsis
Hydrodynamic dtmensions of polymer cotis III solution were investgated around the theta point for the polystyrenecyclohexane system by quasielastic h&t scattering. Below the theta point, the hydrodynamic radius decreases very slighti~ and does not etiblt the collapse of the cod near the cntlcal solution temperature in contrast with the radius ofg~~%tion.

Liquid chromatography of polystyrene standards at the exclusion-adsorption transition point was undertaken with silica adsorbents of different porosity in various eluents. To better understand the elementary phenomena involved in these peculiar conditions, we have investigated by viscometry and ligh
The rotational and the translational diffusion coefficients of G-actin in solution have been obtained by polarized and depolarized dynamic light scattering, respectively. Modeling the shape of the molecule. by a biaxial ellipsoid of revolution, the hydrodynamic dimensions were calculated from the Pe
We present a study of solutions of the site-site Omstein-Zemike equation in the hypemetted chain (HNC) approximation (the extended RISM equation) in the critical region for diatomic fluids modeled with site-site 12-6 potentials and point charge dipoles. The results exhibit anomalies beyond those fou
