    Abstract: Catalyst compositions and polymerization systems include at least one thiourea complex according to Formula (I): MQaX4-a (I) in which M is Ti, Zr, or Hf; a is 1 or 2; each group Q of the thiourea complex is a bidentate thiourea ligand bound to the metal center and having Formula (Ia), Formula (Ib), or Formula (Ic): (Formulas should be inserted here). In Formulas (Ia), (Ib), and (Ic), each group R1, R2, and R3 is independently chosen from alkyl groups or aryl groups; each group Z1 or Z2 is independently chosen from alkylene groups. If a=2, groups R1 of the two groups Q are optionally linked, or groups R3 of the two groups Q are optionally linked. Each X is covalently bonded or coordinated to the metal center and is independently chosen from alkyl groups or halides. The polymerization systems may be configured to copolymerize ethylene and ?-olefins.
