The viscosity of sodium carboxymethylcellulose (CMC) in aqueous sucrose solutions in the presence of sodium chloride was measured by using the viscometer of Ubbelohde type and the influence of added sucrose for aqueous CMC solutions was examined. Judging from the reuslts it has been recognized that the relative viscosity η/η_w (η_w : viscosity of water) increases with the increase of sucrose concentration but decreases with the increase of sodium chloride, and that η/η_o(η_o : viscosity of solvent) decreases with the increase of sucrose at low concentration of sodium chloride, but does not change at a high concentration of sodium chloride and decreases sharply with the increase of sodium chloride concentration. Intrinsic viscosity [η] of aqueous sucrose solution, calculated with Fuoss equation [numerical formula] decreased with the increase of sucrose concentration. This phenomenon indicates the contraction of polymer molecule by the addition of sucrose and it is considered to be due to the dehydration by sucrose.
