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
## Abstract A modification of a viscometer originally proposed by Zimm and Crothers in 1962 is presented, which may be used to measure ultra low shear viscosity for highly dilute polymer solutions. This may provide useful information on polymer coil dimensions and relaxation time. Use of the low sh
## Abstract The apparent viscosities of aqueous solutions of sodium carboxymethylcellulose (NaCMC) and __k__βcarrageenan have been measured over a range of shear rates from 14 to 1142 s^β1^. Comparable measurements were also made on gum solutions to which glucose, sucrose, or glucose syrup had been
