Abstract
Octahydrofluorenyltitanium metal complexes or ring substituted octahydrofluorenyltitanium metal complexes wherein the metal is in the +2, +3 or +4 formal oxidation state and activating cocatalysts or activating techniques are used to produce catalysts useful for polymerizing prochiral olefins to form highly syndiotactic polymers.
