“…Basically, the stability of a miniemulsion system is controlled by the hydrophobe, which acts as an osmotic agent stabilizing the system against Ostwald ripening, and by the surfactants which suppress the coalescence of the droplets. The stabilization of the nanoparticles formed is dependent on a combination of the effects due to the presence of surfactants and an osmotic pressure agent [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The homogenization of miniemulsion nanoparticles is strongly dependent on the energy transferred to the reaction medium according to the preparation technique used.…”

In a conventional semi‐batch seeded emulsion copolymerization of vinyl acetate/butyl acrylate (VA/BA) using hybrid surfactants namely, dioctyl sulfosuccinate (DOSS) as an anionic surfactant, nonylphenol ethoxylate (KENON 30) as a non‐ionic type, and polydimethylsiloxane surfactant (having hydrophilic silanol‐terminated, called PDMS). The effect of PDMS on the properties of the latex synthesized was investigated by measuring solid content, viscosity, colloidal stability, particle size distributions of the base latex, viscosity average molecular weight (M¯v) of the copolymer, latex particle morphology, glass transition temperature (Tg) of a copolymer and thermal gravimetric analysis (TGA). Particle size of the base latex decreases (Z‐average from 246.48 to 143.69 nm) upon increasing the amount of PDMS surfactant in the recipe (up to 6 wt%). The presence of PDMS surfactant in the hybrid surfactants led to a significant increase in the solid content (from 48.71 to 51.31 wt%), viscosity (from 334 to 806 centipoise, cp) and M¯v (from 1.91 × 105 to 2.34 × 105 g mol−1). Thermal stability and Tg of the copolymer were increased with addition of PDMS surfactant (thermal stability from 344.77 to 389.81 °C and Tg from −20.7 to 21.7 °C). The colloidal stability evaluated using the electrolyte addition method was improved with addition of PDMS surfactant. The uniform morphological structure of the final particle is the main effect of using PDMS in the hybrid surfactants.

This review summarizes the background and recent advances of block copolymer stabilized oil‐in‐oil emulsions. For non‐polymerizable emulsions which have promising application possibilities for biomedical and cosmetic formulations, it is shown that tailor‐made block copolymers are by far the most efficient stabilizers with respect to low molecular weight surfactants. The characteristic features of oil‐in‐oil emulsions comprising one polymerizable phase are described. These types of non‐aqueous emulsions are of interest as nanoreactor systems for the polymerization of moisture‐sensitive monomers or catalysts. Furthermore they are the starting point of novel heterophase polymerization processes for the preparation of sterically stabilized polymer particles, as well as of ‘liquid‐filled polymeric materials’. The concept of oil‐in‐oil emulsions is finally extended to those systems where the two phases are polymerizable by distinct polymerization mechanisms. This approach could offer attractive possibilities for the development of special coatings with neither water nor solvent evaporation in their drying or curing step.
