    Rheological properties of carboxymethyl cellulose (CMC .

    May 31, 2008· In this study, we investigated the way of predicting two critical concentrations of sodium carboxymethyl cellulose (CMC) solutions using simple experimental procedures with a rotational rheometer. It was found that, above a critical shear rate, all CMC solutions (0.2 to 7 wt.%) exhibit shear-thinning behavior and the flow curves could be described by the Cross model.

    Carboxymethylcellulose (CMC) - Home | London South Bank .

    CMC molecules are most extended (rod-like) at low concentrations, but at higher concentrations the molecules overlap and coil up and then, at high concentrations, entangle to become a thermoreversible gel. Increasing ionic strength and reducing pH both decrease the viscosity as they cause the polymer to become more coiled.
