Dispersion of liquid–liquid systems is commonly applied in industrial processes such as extraction, suspension, and emulsion polymerization. This article describes the influence of the quality of emulsification on the course and outcome of a batch-emulsion polymerization of styrene and vinyl acetate. From visualization experiments and polymerizations in combination with reaction calorimetric st...
kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using redox initiators (tbhp/fe2+/edta/asac and tbhp/fe2+/edta/sfs) at relatively low temperatures and thermal initiators (bpo, kps and aibn) at higher temperatures to seek the most suitable initiator system. at the end of all reactions the unreacted monomer content was r...
Pickering emulsions differ from classical emulsions, because the first are stabilized by solid particles instead of surfactants. This type of emulsions has been widely investigated in pharmaceutical and cosmetic fields since they present less adverse effects than the classical emulsions that are stabilized by surfactants. The present study was conducted in order to characterize physically and c...
This work describes a strategy to mitigate the undesirable transport of small molecules among aqueous droplets immersed in fluorinated oil by replacing surfactant molecules with nanoparticles as emulsion stabilizers (Pickering emulsions). Amphiphilic silica particles were synthesized and redispersed in fluorinated solvents, and monodispersed picoliter aqueous drops were generated from flow-focu...
