Metal-Chelate Polymers: Structural/Property Relationships as a Function of the Metal Ion.

Abstract

Polymers containing metal ions can exhibit properties quite different from the parent polymers from which they are derived. Metal ions added to preformed polymers can produce marked property changes, especially when the metal modifies the polymer backbone, as is the case in some of the polymeric hydrazones we have ben investigating. When polymer syntheses are designed to place the metal ion directly in the backbone, even more pronounced differences are possible. Classically, planar arrays with conjugated ligands were used for thermal stability but they tend to produce intractability and yield only low molecular weight species. We are evaluating several methods which can minimize such intractability, including: oxe metal ions, such as uranyl (VI); bulky ligands, such as alkyl substituted ligands; and nonrigid eight-coordinate centers, such as tungsten(IV).
