Treatment of (EBI)ZrMe2 with B(C6F5)3 and 100 equiv of 1-hexene in toluene-d8 at -40 degrees C for 1 h, followed by addition of5 equiv of propene, generates a living polypropene catalyst (3) with a polyhexene "tail". Upon further addition of propene,

The propagating species for 1-hexene, propene, and ethene polymerization as catalyzed by [rac-(C2H4(1-indenyl)2)Zr(CH3)][CH3B(C6F5)3] has been intercepted at T-40 degrees C and characterized by NMR methods. Observation of the propagating species perm
