    Abstract: A polymerisation catalyst comprising:

    (A) rare earth metal component selected from the group consisting of (1) a reaction mixture obtainable by treating a silica support, a carbon black support or a mixed support thereof with a mono- or di-ethyl aluminium chloride, adding a neodymium carboxylate in the presence of a solvent to form a slurry, and removing the solvent or (2) a reaction mixture obtainable by dissolving a neodymium carboxylate in a first solvent, adding silica or carbon black, and removing the solvent to obtain a dry solid, contacting the dry solid with a solution containing a mono- or di-ethyl aluminium chloride in a second solvent, and removing the second solvent; and
    (B) a co-catalyst selected from the group consisting of a diisobutyl aluminium hydride, triisobutyl aluminium, and a mixture thereof.
