摘要:
A process for the preparation of polymer magnetic particles, which comprises: (a) providing a water phase containing magnetic components homogeneously dispersed therein; (b) wherein the water phase is contacted with or further contains a polymerisable metal-containing or organic monomer which is soluble in the water phase; and (c) polymerizing the monomer in the presence of the magnetic in which the magnetic components are substantially uniformly distributed; wherein at least a part of the polymerizing step (c) is carried out in a water-in-oil emulsion in which the water phase containing the magnetic components homogeneously dispersed therein is present as a discontinuous phase in a continuous oil phase.
