33. General polymerization procedure: Flow of ethylene gas (100 L/h) was charged into 250 mL of toluene at 25 °C. To this solution, MAO (Albemarle MAO, 1.2 M toluene solution) and a toluene solution of a complex was added at the desired polymerization temperature. After the prescribed time, 25 mL of isobutyl alcohol was added to terminate the polymerization.
34. Although initiation efficiency cannot be discussed accurately for such low polymer yields, the values suggest the high efficiency for generating active species.
