Effect of pH on steady-shear viscosity of CMHA solutions.

<p><b>A:</b> Steady-shear viscosity at a shear rate of 25 s^-1 for solutions of mock CMHA and CMHA (25 mg/ml) in 0.9% NaCl (saline). Mock CMHA has 0% CM modification; CMHA has 33% CM modification. <b>B:</b> Steady-shear viscosity at a shear rate of 25 s^-1 for solutions of CMHA (25 mg/ml) in 0.9% NaCl (saline) or DI water. CMHA has 25, 33, or 74% CM modification as indicated in the legend by the number following CMHA.
