Abstract

The behavior of aqueous dispersions of Carbopol (Carbopol ETD 2050) in the microgel state at low weight concentrations is considered. Flow curves and the frequency dependence of dynamic moduli are approximated at specific shear rate and frequency intervals using the equations of a structural rheological model. Flow types corresponding to different states of the microgel structure are shown. Two types of oscillatory flow are shown, existing at specific shear frequency intervals. The values of the rheological equation coefficients, which are discussed within the framework of the structural model, are presented.
