摘要： The present disclosure relates to ansa-metallocene catalyst compounds, catalyst systems comprising such compounds, and uses thereof. In some embodiments, a catalyst compound is represented by Formula (I):


TyLAMXn-2   (I),

wherein: M is a group 3-6 metal; n is the oxidation state of M; A is a monocyclic or polycyclic arenyl ligand bonded to M and is substituted by at least one phenanthridin-5-yl substituent; L is a monocyclic or polycyclic arenyl ligand bonded to M; T is a bridging group; y is 1 or 0; and each X is independently a univalent anionic ligand, or two Xs are joined and bound to M to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand.
