Micrometer‐sized magnetic particles hosted on network material were successfully prepared by a simple chemical process (ion exchange followed by co‐precipitation) from commercial styrene‐divinylbenzene copolymers. Energy dispersive X‐ray spectroscopy (EDS) coupled to scanning electron microscopy (SEM) allowed the observation of submicron particles. All the produced spherical beads have presented metallic particles (NiFe 2 O 4 , CuFe 2 O 4 , CoFe 2 O 4 , or MnFe 2 O 4 ), either as isolated particles or agglomerates, located on their external and internal (within pores) The thermal stability of the composites, evaluated by thermogravimetric techniques, were found to be dependent on the amount of ferrite particles incorporated into them.
