The elaboration of polystyrene latex particles decorated by silica nanoparticles is realized through an emulsion polymerization process. The aim is to study the influence of some parameters such as the initial composition, reactants nature, or the way to insert reactants in the reaction medium, and observe the effects on the created hybrid particles. Therefore, adding the monomer continuously allows a smaller particle size distribution. The selection of the amphiphilic compound has an influence on the affinity of the particle surface. The choice of the initiator is also important to get decorated latex particles.
