The model of Ouchiyama and Tanaka1–3 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 ).
