ABSTRACT:
The present invention relates to a magnetically active organometallic Schiff base polymer having a molecular weight of between about 4,000 and 50,000 daltons. In an additional aspect, the present invention relates to a process for the preparation of magnetically active organometallic polymer having a molecular weight of between about 4,000 and 50,000 daltons, wherein the polymer comprises a multiplicity of Schiff base tridentate chelating groups having the capacity to combine with the iron (II) or iron (III) ion of an organic salt, which process comprises:
