This work is a complete and comprehensive study of the rheological properties of carboxymethyl cellulose (CMC) solutions. The study was carried out using the computer controlled RheoStress RS100 system of Haake. CMC concentration in the test solutions ranged by weight from 1 to 5%. This range was sufficiently wide to reveal the nearly Newtonian behavior at the lower end of concentrations, and the definitely pseudoplastic, thixotropic, and viscoelastic behaviors of CMC solutions at the higher end of concentrations. The scope of the study included measurements of steady‐state parameters, transient shear stress response, and yield stress. In addition, the thixotropic, creep recovery, and dynamic responses of solutions with high concentrations were measured. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 289–301, 1997

A comprehensive study of the rheological properties of aqueous polyacrylamide solutions was carried out. A RheoStress RS100 Haake rheometer was used in the measurements. The concentration of polyacrylamide ranged from 0.25 to 1.0% by weight. This range is sufficiently wide to cover many of the rheological features of polyacrylamide in the lower range of concentration. The study included measurements of steady shear flow parameters, transient shear stress response, yield stress, thixotropic behavior, creep recovery, dynamic responses, and temperature effects in the range 10-50ЊC.

Poly(dimethylsiloxane) solutions are widely used in coating mixtures of many industrial coating processes. The flow of these solutions in and around the coating devices is strongly dependent on their rheological properties. This work presents a comprehensive experimental study of these properties. The tests were carried out for two poly(dimethylsiloxane), PDMS, solutions with vastly different viscosities, 1000 and 30 000 mPa·s. The measurements were taken on the RheoStress RS100 rheometer of Haake, over the range of temperatures 10−50 °C. The solutions were tested for steady shear values, thixotropic behavior, transient shear stress response, yield stress values, creep−recovery response, and dynamic response.
