N2 - The paper is focused on the growth of polystyrene particles followed by optical microscopy during dispersion polymerization (DP) in the absence of crosslinking agents. In particular, we compared the growth kinetics of the particles and their tendency to coagulation in alcoholic media in the presence of a steric stabilizer, chosen from one of the following: polyvinylpyrrolidone (PVP-40, PVP-10, PVP-360), hydroxypropyl cellulose (HPC), poly(acrylic acid) (PAA), and polyvinyl alcohol (PVA). The particle size distributions from the optical microscopy images were obtained using trained neural network. To predict the particles’ growth at the first few hours after microphase separation, we suggest to adopt a simple model describing the coalescence of liquid drops in immiscible fluids. Based on this model, we discuss the possible approaches for the preparation routes of the particles with non-spherical morphology.
