Abstract: The method of dissymmetry of scattering of light radiation applied to monodisperse PS latices with particle diameters of 98 or 215 nm was used for modelling the course of their rapid coagulation. The changes in dissymmetry found experimentally during aggregation were in good agreement with theoretical values and on the basis of them some information about the apparent size of aggregates is to be obtained. It has simultaneously been shown that the presence of aggregates does not affect the determination of size of primary latex particles from dissymmetry data performed at a characteristic pair of angles and wavelength.
