ABSTRACT:
Olefins are polymerized by the use of catalysts comprising biscyclopentadienyl, Group 4 transition metal complexes formed with conjugated dienes wherein the diene is bound to the transition metal either in the form of a .sigma.-complex or a .pi.-complex in combination with activating cocatalysts.
