Three acrylate monomers featuring different side-groups are synthesized in yields up to 94% in a one-pot procedure using the versatile Passerini-three-component reaction. The procedure for their miniemulsion polymerization into polymeric particles with tunable sizes is established. Ethylene glycol dimethacrylate is introduced as comonomer to induce crosslinking and enable the production of microgels. Besides the shelf life of the miniemulsions, the dependence of the particle size on the concentration of the surfactant (sodium dodecyl sulfate) and the crosslinker, as well as the sonication amplitude and time, is investigated. The particle size of the collapsed microgels range from 21 to 91 nm. The swelling of the microgels in organic solvents is studied.
