Abstract：Oil-based Fe3O4 magnetic fluid was prepared using FeCl3·6H2O and FeCl2·4H2O by chemical coprecipitation method and the process route was chosen to overcome the agglomeration difficulty of magnetic particles in the synthesis process of Fe3O4 magnetic fluid. The magnetic fluid had good dispersion and stability, and its saturation magnetization was up to 72.60 emu/g. P(St-GMA-DVB) polymer magnetic microspheres were synthesized by suspension polymerization method. The stirring speed had greater impact on magnetic microsphere particle size, and the magnetic microsphere particles were in the range of 55~300 mm. The appearance of magnetic microsphere was monodisperse spherical, and the content of epoxide could be achieved 17 mmol/g.
