To avoid the 0/0-type extrapolation typical for Huggins plots, a new procedure was used. For CMG and pure water, this requires only two adjustable parameters: the specific hydrodynamic volume of the polymer in the limit of infinite dilution and a hydrodynamic interaction parameter. The intrinsic viscosity of CMG (no salt) at room temperature is 6 050 mL . g(-1); approximately half as large as that of Na-PSS of comparable molar mass. The ratio of the intrinsic viscosities with and without salt is approximate to 7 for CMG, as compared to &gt;100 for Na-PSS. The reasons 1:5 5 for the different behaviors of the two types of polyelectrolytes are being discussed.</p>10aBiopolymers10aCarboxymethyl guar10aintrinsic viscosity10apolyelectrolyte10asalt-free solutions1 aBadiger, Manohar, V.1 aGupta, Nivika, R.1 aEckelt, John1 aWolf, Bernhard, A.  uhttps://library.ncl.res.in/content/intrinsic-viscosity-aqueous-solutions-carboxymethyl-guar-presence-and-absence-salt-0
