Abstract (en)

[origin: WO9742161A1] Polysubstituted cyclopentadiene compound, wherein at least one substituent is of the form -RDR'n, where R is a bonding group between the cyclopentadiene and the DR'n group, D is a hetero atom chosen 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 which at least one further substituent is a linear alkyl group comprising at least 2 carbon atoms. 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.
