Abstract (en)

[origin: WO9742162A1] Polysubstituted cyclopentadiene compound, in which at least one substituent is of the form -RDR'n', in which R is a bonding group, D is a hereto atom selected from group 15 or 16 of the Periodic System of the Elements, R' is a substituent and n is the number of R' groups bonded to D, and in that at least one further substituent is a branched alkyl group. Metal complexes in which at least one of these cyclopentadiene compounds is present as a ligand are useful as catalysts for the polymerisation of alpha-olefins.
