Metallocene polymers characterized as being in a stacked configuration where the monomeric units are constrained to interact with one another across their cofacial cyclopentadienyl ring surfaces, and having the general structure <IMAGE> where M represents the metal and n is an integer of 2 or greater. The preparative method involves the coupling reaction between a zincated metallocene and a dihalogen-substituted aromatic, in the presence of a catalyst. The mixture is refluxed, and the resultant polymer is taken up in organic solvent, washed, dried, separated and purified.
