Procedure

30 wt % MAO in toluene (6.27 g, 32.4 mmol, 120 eq.) and toluene (6.50 g) were combined and stirred for 15 minutes to give a clear solution. To this MAO solution was added dimethylsilylene(2,3,4,5-tetramethyl-1-cyclopentadienyl)(3-(4-t-butylphenyl)-1-indenyl)zirconium dichloride (Metallocene II, 0.158 g, 0.269 mmol, 1.00 eq.). The reaction was stirred for 15 minutes and then DAVISON™ 948 silica (5.00 g, dried at 600° C. for 16 hours) was added. The slurry was mixed for 10 minutes and then dried under vacuum for 24 hours. Yield 6.92 g (98%).
