| titleOfInvention | Thiourea Group IV Transition Metal Catalysts and Polymerization Systems |
| abstract | The catalyst composition and polymerization system comprise at least one thiourea complex according to formula (I): wherein M is Ti, Zr, or Hf; a is 1 or 2; Each Q group of a thiourea complex is a bidentate thiourea ligand attached to a metal center and has Formula (Ia), Formula (Ib), or Formula (Ic): In formulas (Ia), (Ib), and (Ic), each group R 1 , R 2 , and R 3 is independently selected from an alkyl group or an aryl group; Each group Z 1 or Z 2 is independently selected from an alkylene group. When a=2, the groups R 1 of the two groups Q are optionally linked, or the groups R 3 of the two groups Q are optionally linked. Each X is covalently bonded or coordinated to a metal center and is independently selected from an alkyl group or halide. The polymerization system may be configured to copolymerize ethylene and α-olefins. |
