22. 3 (1.00 mL, 1.0 μmol) was added to the reactor with vigorous stirring (1200 rpm) to initiate polymerization. After a prescribed time, the polymerization was quenched by an injection of i-butyl alcohol (10 mL).

24. n displayed much reduced activity at elevated temperatures (e.g., 25°C: 59000 kg-PE/mol-cat/h, 75°C: 8600 kg-PE/mol-cat/h), indicating that the phenoxy-imine ligand plays a role of vital importance in realizing the thermally robust V-based catalyst system.
