| Abstract: | A newly developed theory about solute adsorption effect in viscometry of polymer solution was reviewed and extended for measuring the adsorbed layer thickness. Examples were given for the characterization of six polystyrene samples with different molecular weights by measuring their solution viscosity in benzene. |
