摘要:
Catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers 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 a cocatalyst or subjected to bulk electrolysis in the presence of compatible, inert non-coordinating anions.
