|a This work characterized colloidal stability of the dispersions, formed by the complexes of poly(ethylene oxide)-b-poly(sodium methacrylate) and hexadecyltrimethylammonium bromide. At room temperature, the dispersion was stabilized by the poly(ethylene oxide) (PEO) chains and did not aggregate for at least several months. Elevation of temperature caused aggregation of the dispersion because of dehydration of the PEO chains. At initial stages (minutes), the aggregation was reversible and the particles spontaneously redispersed once the temperature was decreased. However, it became irreversible at the later stages (hours), probably indicating fusion of the hydrophobic cores of the BIC particles. Addition of elementary salts led to a decrease of the aggregation temperature. The effects of various salts were dependent on the chemical nature of the ions and were consistent with the Hofmeister series. This behavior was discussed in terms of hydration and London (dispersion) interactions between the ions and the PEO
