A new strategy for the preparation of magnetite/silica/(co)polymer core/shell nanoparticles is described. The reversible addition‐fragmentation chain transfer/macromolecular design via interchange of xanthates (RAFT/MADIX) polymerization agent — xanthate/dithiocarbonate — is covalently anchored to the aminosilica‐coated iron oxide nanoparticles surface by its R‐group. Subsequently, polymerization and copolymerization of vinyl monomers on such synthesized structures are carried out. Fourier transform infrared (FTIR) spectroscopy, UV–vis spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X‐ray diffraction (XRD), energy‐dispersive X‐ray (EDX) analysis, and transmission electron microscopy (TEM) are employed to confirm the grafting and study the chemical composition of the obtained structures.
