Droplets nucleation is the distinctive features of miniemulsion polymerization. During this polymerization processes

the need for mass transfer of the monomers through the aqueous phase is minimized even neglected.Thus

materials that are not easy to be prepared by other polymerization techniques can be obtained

such as superparamagenetic latex particle

high solids low viscosity latexes

encapsulation of inorganic solids.This article deals with the fundamental aspects involved in the preparation and polymerization of monomer miniemulsion.The applications of miniemulsion polymerization are also reviewed.
