Effect of Urea Concentration on the Viscosity and Thermal Stability of Aqueous NaOH/Urea Cellulose Solutions

Figure 8

Absorbance profile in the OH stretching region during gelation of SS with 6% added urea. Background was SSb with 6% added urea at the same experimental stage. The dashed curves show the two Gaussian peaks used to deconvolute the OH peak of cellulose.
