Abstract (en)
[origin: WO9958539A1] A class of metallocene compounds is disclosed having the following general formula (I): Rn(Cp)(A)MLp wherein Rn is a structural bridge; Cp is a heterocyclic cyclopentadienyl group of formula (II) wherein R<1> and R<2> are hydrogen or hydrocarbon groups; M is a transition metal of group 3, 4, 5 or 6 or to the lanthanides or the actinides in the Periodic Table or the Elements (new IUPAC version); L is a monoanionic ligand; Z is NR<3> or O; X and Y are selected from (CR<4>2)n, BR<4>2, PR<4>, SiR<4>2 or GeR<4>2; and substituents R<4> are hydrogen atoms or hydrocarbon radicals, with the proviso that both X and Y cannot be carbon atoms at the same time; A is a group selected from substituted or unsubstituted cyclopentadienyls, which may carry one or more condensed cycles, =NR<5>, -O-, -S- and =PR<5> groups, R<5> being defined as substituents R<1> and R<2>, and groups corresponding to formula (II); p is an integer from 0 to 3. These metallocene compounds are useful as catalyst components for the polymerization of olefins.
