Description	Aqueous polymer solutions commonly display both non-Newtonian bulk rheological behavior and apparent slip at liquid-solid interfaces (AWS effect). The AWS effect becomes important when transport characteristics like viscosity or diffusivity are experimentally determined in measuring instruments with small hydraulic radii, e.g. in extremely narrow channels, commonly encountered also in micro-reactors, membrane and similar processes. The AWS effect is an interfacial phenomenological property and, hence, it can depend on the bulk material of the confining walls and on the surface finishing, as well. The proposed paper is focused on experimental viscometric study of AWS effect of aqueous polymer solutions: 1.5% wt solution of Na salt of Carboxymethylcellulose, 0.4%wt of Welan Gum and 1% wt of Polyacrylamide was chosen as the tested liquids. It is documented that the extent of AWS effect strongly depends both on the sensor material and type of solution.
