Zusammenfassung:	The polymerization method to prepare monodispersed organic/inorganic composite nano microsphere comprises: preparing two different fine emulsion systems of A with inorganic nano particles and B with poly-monomer; adding water-soluble initiator into A, stirring till complete dissolution, then adding B to stir till mixing evenly; finally, heating the mixed system at given temperature for isothermal reaction. The product of superparamagnetic Fe3O4/polystyrene has homogeneous grain size, and controllable size and magnetic content. This invention is practical and convenient to realize large-scale production.
