“…For these cases, miniemulsion polymerization is particularly well suited. The preformed step‐growth polymer(s) is (are) dissolved in the monomers to be polymerized by free‐radical polymerization and the mixture dispersed in water using a homogenization device . Then, the monomers contained in the composite droplets are polymerized by adding an initiator.…”

Hybrid waterborne dispersions provide improved performance in established applications and allow targeting new applications that are out of reach of the conventional homogeneous latexes. They are product‐by‐process materials that are produced by either emulsion or miniemulsion polymerization and whose characteristics are determined in the reactor. Therefore, it is crucial to produce them by means of an optimal process strategy. This work reviews the fundamental knowledge available as well as the missing parts needed to develop such strategy focusing on particle morphology, which is the most distinctive feature of these materials.

“…The incorporation of preformed polymer in miniemulsions can affect the droplet size, depending on its concentration and its molecular weight [Lopez et al, 2008;Blythe et al, 2000]. Colmán et al (2011) investigated the effect of adding 10-20% of polystyrene (PS) and Poly(methyl methacrylate) on the kinetics and nucleation mechanism of ME homopolymerizations of St and MMA, employing KPS as initiator.…”

-In miniemulsion polymerization, droplet nucleation is the key factor to ensure the production of polymer particles with a desired composition. The influence of the initiation on droplet nucleation is conflicting and it has not been completely considered. The result of employing different initiator systems on the nucleation mechanism and kinetics in the polymerization of stable styrene/polystyrene miniemulsions with varied droplet size is discussed here. The initiation systems employed provide all combinations between the phase (aqueous or organic) where initiation mainly occurs and the phase affinity of the produced radicals. Latexes with different contributions of droplet nucleation were synthesized according to the employed initiation system and the droplet size of the miniemulsion. The results presented here could be used as a guide for choosing the initiation system to achieve the required contribution of droplet nucleation.

“…HPH is a suitable technique to produce submicron droplets at a high throughput [17]. However, it has to be mentioned that HPH so far has been rarely used to prepare miniemulsions for polymerization [11,14].…”

“…Technical processes to disrupt droplets include static mixers [8,9], rotor-stator systems [9][10][11], ultrasound devices [9,12,13], and high pressure homogenizers [11,13,14]. Depending on the process, the resulting droplet size distribution is determined either by the type and concentration of the surfactant, which is needed to stabilize the monomer droplets, or by the energy input [13,15].…”

Composite nanostructured particles can be produced by polymerization of monomer miniemulsion droplets loaded with inorganic nanoparticles. The article gives an overview on the development of a scalable continuous process for the production of such hybrid nanoparticles via miniemulsion polymerization. Different possibilities for the necessary surface modification of the inorganic material are discussed in detail. Furthermore, the influence of the surfactant concentration on the droplet size after emulsification as well as on the nucleation mechanisms during polymerization is highlighted. Possible process routes for the emulsification of the nanoparticle-loaded monomer phase are compared taking into account different process and material parameters, such as energy consumption, abrasion, dispersed phase viscosity, inorganic particle load and size, and morphology of the resulting hybrid particles. The possibility of an industrial implementation via an integrated high pressure homogenization process and a subsequent continuous polymerization are presented.
