摘要:
This invention relates to metallocene compounds represented by formula (I): (I) Where in M is a group 3, 4, 5 or 6 transition metal atom, or a lanthanide metal atom, or actinide metal atom; E is an indenyl ligand that is substituted in any position of the indenyl ligand with at least one aromatic heterocyclic substitutent or pseudoaromatic heterocyclic substituent that is bonded to the indenyl ring through a nitrogen or phosphorous ring heteroatom, and additionally, E may be substituted with 0, 1, 2 , 3, 4, 5 or 6 R groups, where each R is, independently, a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, substituted silylcarbyl, germylcarbyl, or substituted germylcarbyl substituent, and optionally, two or more adjacent R substituents may join together to form a substituted or unsubstituted, saturated, partially unsaturated, or aromatic cyclic or polycyclic substituent; A is a substituted or unsubstituted cyclopentadienyl ligand, a substituted or unsubstituted heterocyclopentadienyl ligand, a substituted or unsubstituted indenyl ligand, a substituted or unsubstituted heteroindenyl ligand, a substituted or unsubstituted fluorenyl ligand, a substituted or unsubstituted heterofluorenyl ligand, or other mono-anionic ligand, or A may, independently, be defined as E; Y is an optional bridging group that is bonded to E and A, and is present when y is one and absent when y is zero; y is zero or one; X are, independently, univalent anionic ligands, or both X are joined and bound to the metal atom to form a metallocycle ring, or both X join to form a chelating ligand, a diene ligand, or an alkylidene ligand; and provided that when A is independently defined as E, and y is one, and Y is bonded to the one position of each indenyl ligand, and per indenyl ligand there is only one aromatic heterocyclic substitutent or pseudoaromatic heterocyclic substituent that is bonded to the indenyl ligand, such substituent being bonded to the 4-position of the indenyl ligand, then such substituent is not an unsubstituted or hydrocarbyl substituted pyrrol-l-yl substituent including ring-fused hydrocarbyl substituted pyrrol-l-yl substituents such as indol-l-yl, isoindol-2-yl, carbazol-9-yl, 2,3,4,9-tetrahydrocarbazol-9-yl, and 1,2,3,4-tetrahydrocyclopenta[ b ]indol-4-yl. This invention further relates to a catalyst system comprised of the above metallocenes combined with an activator, and to a process to polymerize unsaturated monomers using such catalyst system.

This invention relates to novel bridged a hafnium transition metal metallocene catalyst compounds having two indenyl ligands substituted at the 4 positions with a C 1 to C 10 alkyl, where the 3 positions are hydrogen (assuming the bridge position is counted as the one position) and the bridging atom is carbon or silicon which is incorporated into a cyclic group comprising 3, 4, 5, or 6 silicon and/or carbon atoms that make up the cyclic ring.
