A model composed of a synthesis the nonlinear Cahn−Hilliard and Flory−Huggins theories for spinodal decomposition (SD) second-order rate equation self-condensation trifunctional monomer is presented used to analyze polymerization-induced phase separation (PIPS). The numerical results replicate frequently reported experimental observations on PIPS binary monomer−solvent solution. These include transient periodic concentration spatial profile with wavelength that decreases increasing constant....

The numerical results are consistent with experimental observations. These observations include formation evolution droplet-type morphology. In addition, time maximum value structure factor S(km,t) exhibits an exponential growth...
Abstract Electrical resistance tomography (ERT), which is a non‐invasive and robust measurement technique, was employed to visualize, in three dimensions, the concentration field inside cylindrical mixing vessel equipped with radial‐flow Scaba 6SRGT impeller. The ability of ERT work opaque fluids makes this technique very attractive from an industrial perspective.
