Novel polymeric diphosphine coordinates are obtained by reacting a diphosphine alkali alcoholate with an halogenated polymer, and their metal derivatives are obtained by reacting the coordinate with salts or transition metal complexes. These metal polymers can be used as catalysts in catalysis reactions by means of coordination complexes.
