“…The similar estimations performed in [64] give the critical diameter about 500 nm, whereas according to [65] this value is about 300 nm. Note, the same conclusion was obtained in one of the earliest experimental studies on coagulation of polystyrene latex [66]: the large particles (above 700 nm) are undergoing the reversible flocculation in the secondary potential well, whereas small particles (below 500 nm)…”

The experimental evidences and available theoretical explanations on formation of stable clusters in colloidal suspensions are reviewed. The clusters form in the parameters range intermediate between that corresponds to a stable suspension built up by singlets and that causing the irreversible coagulation of the suspension. The stable clusters can appear as a result of a competition between a short range attraction and a long range repulsion between colloidal particles or due to reversible flocculation in the shallow secondary potential well.

“…4). A similar dependence has been observed for emulsifier-free polymerization of styrene initiated by potassium persulfate [6,7]. The negative concentration effect of high concentrations of water-soluble ionic initiators is due to an increase in the ionic strength of the reaction mixture and in the concentration of surfactant oligomers, which can form new PMPs in the course of polymerization, thereby making the latexes polydisperse.…”

“…The dependence of the flocculation rate on the particle size has long been a subject of intensive study and numerous reports have been published on this topic using a variety of theoretical approaches (14)(15)(16). Regarding the stability of thin liquid films, the problem of coalescence of two liposomes is effectively the same as the problem of rupture of the liquid film formed between the liposomes (see Fig.…”
