Aspects on the synthesis of polymers with a core-shell structure obtained from suspension polymerization, which is used in vascular embolization, are described elsewhere [3,12,13]. In this scenario the synthesis of polymer/inorganic hybrids has also been exemplified by our research group [14,15]. As a representative example of embolic agents, magnetic copolymers of poly(vinyl acetate) (PVAc)/poly(vinyl alcohol) (PVA) with a core-shell structure have high potential for the treatment of tumors and hyperthermia therapy of injured areas. The implementation of this process is possible by adhering superior control of the reaction system, which will produce particles of similar morphology comparable to the substance precursor.

A completely different strategy to synthesize polymer/inorganic hybrid nanoparticles in miniemulsion is the solvent evaporation technique. Instead of a monomer droplet that polymerizes after sonication, a pre-formed polymer is dissolved in an organic solvent such as chloroform or toluene [30], This polymer solution forms the dispersed phase of the miniemulsion. Evaporation of the solvent from the miniemulsion droplets leads to precipitation of the polymer and the formation of nanoparticles. This technique could also allow for the synthesis of hybrid...
