Metallocene that is polymerizable by free radical catalysis and has metal nucleus in a state of oxidation below its maximum can be polymerized without oxidation of such nucleus by forming a reaction mixture containing said metallocene and the reducing agent of a redox catalyst combination, then initiating and maintaining polymerization of said metallocene with the gradual addition of the oxidizing agent of said combination to said reaction mixture.
