Propene and 1-octene were copolymerized with the syndiospecific homogeneous metallocene catalyst Me2C(Cp)(Flu)ZrCl2/MAO. Large amounts of octene were incorporated randomly. While catalyst activity was not affected markedly by low octene content, mole

Propene polymerization of methylalumoxane (MAO) activated rac-Me2Si(Benz[e]Indenyl)2ZrCl2 (BI) and rac-Me2Si(2-Me-Benz[e]Indenyl)2ZrCl2 (MBI) was studied to investigate the influence of the ligand substitution pattern and the role of dormant sites. P
