| Abstract: | With oleic acid functionalized Fe3O4 nanoparticles as the magnetic carriers, styrene and crylic acid as the monomers, and divinylbenzene (DVB) as cross linker, the magnetic polystyrene microspheres were prepared by disperse polymerization. A series of characterizations show that as prepared magnetic polystyrene microspheres have narrower size distribution with smoothsurface, fine morphology and structure. The as prepared microspheres are pretty superparamagnetic, the specific saturation magnetization of them reaches to 11.61 Am2/kg at room temperature. |

| Keywords: | magnetic microsphere disperse polymerization preparation superparamagnetic |
