Modelling of The Rheological Properties of Bimodal Emulsions

The model of Ouchiyama and Tanaka 1 - 3 was successfully adapted to calculate the maximum packing fraction (ϕ_m) of polymer latexes with varying bimodal particle size distributions based upon rheological measurements performed on its constituent parts. The values of ϕ_m calculated from the model can be used to predict the rheological properties of the latices. The model was experimentally validated and used for the prediction the viscosity of studied bimodal latices of known concentration using the master curve of viscosity-reduced volume fraction (η vs. ϕ/ϕ_m).
