Abstract:

Research on characterization of viscoelastic properties of ultrahigh molecular weight polymer solutions led to the discovery of variations in rheological properties combined with variable dissolution behavior for certain polymer-liquid systems. The reference solutions exhibited extreme intra sample variations therefore, the influence of processing and trace impurities on rheological property variance was studied. Measurements of first normal stress difference, apparent viscosity, and dynamic viscoelastic properties were performed as a function of controlled addition of components with specific molecular interactions with polymers or solvents e.g., various salts, surfactant, and chelating reagents. In addition, processing treatments such as filtration and centrifugation were applied and their influence on rheological properties of the polymer solution was determined.
