2-alkyl-4-(2,6-dialkylphenyl) indenes

2-alkyl-4-(2,6-dialkylphenyl) indenes of formula (I) or II wherein: R1 to R5 are independently hydrocarbyl group, Z is a bridge and in which the double arrow symbol indicates a shift in the position of the double bond. Methods for converting such indenes to bridged metallocene ligands and converting...

Beschreibung
Zusammenfassung:	2-alkyl-4-(2,6-dialkylphenyl) indenes of formula (I) or II wherein: R1 to R5 are independently hydrocarbyl group, Z is a bridge and in which the double arrow symbol indicates a shift in the position of the double bond. Methods for converting such indenes to bridged metallocene ligands and converting such ligands to bridged metallocenes and olefin polymerization processes in which such metallocenes are used as a catalyst or as a component of a catalyst system are described.
