Abstract:
Embodiments relate to a novel catalyst composition comprising a transition metal-containing compound, a PNP compound, an alkylating agent and a fluorine containing compound. Other embodiments relate to a method of polymerizing a diene monomer in the presence of the novel composition to form a diene-containing polymer having greater than 90% cis content.
