Figure 1. Viscosity as function of % w/w polymer solids in aqueous dispersion at pH 6.5–7.5

Thickening is the primary function of rheology modifiers, which change the physical properties of a system and the migration rate of suspended components. Viscosity measurements, shown here, were made on an aqueous dispersion of the polymer, compared with other commercially available inverse emulsion polymers and thickeners selected for benchmarking purposes, at different concentrations of polymer solids.
