Catalyst compositions for use in the polymerisation of olefins comprise neutral metal complexes together with activators comprising non-aromatic boron compounds. Suitable activators are triisobutylboron together with trialkylaluminium compounds. Preferred complexes are metallocenes. The use of such activating systems obviates the need for expensive aluminoxanes or aromatic fluorine containing compounds.
