Abstract

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 (χg) of this organic polymer was between about 1 × 10 −6 cc/g and 1 × 10 −2 cc/g at an ambient temperature. When this polymer, which was a useful tough film, was heated up to about 200 °C and held for approximately 1 minute, the magnetic susceptibility increased from 1 × 10 −4 cc/g to 6 ° 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.
