Abstract
The kinetics of shear-induced coalescence of polystyrene(PS)/poly(methyl me thacrylate) (PMMA) blends containing 1 and 5% PMMA were studied as a functi on of shear rate with rheo-SALS (small angle light scattering). The growth of the average particle size is shown to be a function of total strain inde pendent of shear rate, the growth rate being controlled by the volume fract ion of the dispersed phase. The experimental behavior is quantitatively des cribed by the simulation of the evolution of particle size distribution on the basis of non-linear rate equations including hydrodynamic interactions.
