The effects of high-shear processing and thermal exposure on the molecular weight and solution viscosity stability of selected polymers were studied. Aqueous solutions of two molecular weight grades of hydroxyethyl cellulose (HEC) were subjected to high-shear rates using a high-shear mixer and two c
