Conditions: dimethylsilylene bis(2-methyl-4-phenyl-1-indenyl) zirconium dichloride (Zr), MAO used as a cocatalyst and scavenger with [Al]0:[Zr]0 = 1000:1. Molar ratio of [TIBA]0:[11-Br]0 = 1:10, 0.5 mL toluene, 49.5 mL hexanes, propylene 2 bar, polymerization temperature = 50 °C, 0.5 h. Polymerization was performed at least in duplicate and mean values reported.
kgPP molZr –1 h–1 bar–1.
kgPP gZr –1 h–1.
Determined by 1H NMR spectroscopy.
Determined by SEC using the Mark–Houwink correction for PP.
