摘要：
In the presence of dried methylaluminoxane as an activator, the hafnium(IV) dichloro pre-catalyst 4 incorporating with an [OSSO]-type ligand was found to promote precisely isospecific 1-hexene polymerizations of [mmmm] up to 95 % with fairly high activities (1,050-3,180 g mmol(4)(-1) h(-1)) and relatively narrow polydispersities (M-w/M-n = 1.5-1.8).
