Abstract (en)

[origin: WO0031089A1] The invention relates to a method for purifying metallocenes according to which a poorly soluble metallocene halogenide is transformed into a readily soluble and easily crystallisable metallocene by replacement of at least one halogenide ligand with another, negatively charged, ligand, after which the metallocene obtained in this way is purified by crystallization.
