ABSTRACT:
Polyoxometalates are provided which are highly soluble in organic solvents, including monomer mixtures utilized in reaction injection molding. High solubility is obtained by organic moieties incorporated in the cation and anion of compounds having the formula [R.sup.1.sub.m ER.sup.2.sub.m' ].sub.n M.sub.x O.sub.y L.sub.z. These compounds provide improved solubility while maintaining catalyst activity within reaction injection molding formulations. A method is also provided for preparing these polyoxometalates within an aqueous acidic medium, wherein ligands are incorporated in the complex simultaneously with the formation of the polyoxometalate complex.
