摘要：The present invention provides a simple method for introducing magneticparticles into a polymer for further preparing a magnetic polymer, the method using thecapability of polymer to absorb Fe and other divalent metal ions M, adding alkaliimmediately each time after absorbing Fe or M, thereby generating hydrated oxide ofthe Fe and hydrated oxide of the divalent metal ions in sequence inside the polymer, andthen heating, so that the hydrated oxide of the Fe and the hydrated oxide of the divalentmetal ions are transformed into magnetic particles MFexOy, where M may be Fe, Zn, Mg,Cu, Ca, Ba, Sr, Ni, Co, Mn and the like, and x=1.0˜2.0; y=3.0˜4.0. Compared with the priorart method, the present one is simpler, wider in application, and more operable.
