Iron-Schiff Base Magnetic Polymers, Synthesis and Characterization
A magnetically active organometallic iron-Schiff base polymer, molecular weight was between about 4,000 and 50,000 daltons, was synthesized, This polymer comprised 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. A magnetic susceptibility (chi(g)) of this organic polymer was between about 1 x 10(-6) cc/g and 1 x 10(-2) cc/g at an ambient temperature. When this polymer, which was a useful tough film, was heated up to about 200 degrees C and held for approximately 1 minute, the magnetic susceptibility increased from 1 x 10(-4) cc/g to 6 x 10(-4) cc/g. The surprising permanent residual enhancement of the magnetic susceptibility of this polymer should be useful in the storage of information in optical magnetic devices.
