Effect of Urea Concentration on the Viscosity and Thermal Stability of Aqueous NaOH/Urea Cellulose Solutions
Figure 3
Reduction in viscosity of SS and SPS samples, shown at example of shear rates of 164 and 146 s−1, respectively. A linear fit for each is also shown, with corresponding values at a confidence level of 95%, represented by the grey regions. °C.
