Document Type and Number:

Japanese Patent JP2000512310

Kind Code:

A

Abstract:

It is disclosed a new class of bridged metallocene compounds of formula (I):wherein R1 and R2 can be hydrogen, alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl radicals; R3 and R4 form a condensed, 5- to 8-membered, aliphatic, aromatic or heterocyclic ring; M is a transition metal of groups 3, 4, 5, lanthanide or actinide; X is hydrogen, halogen, -R, -OR, -OSO2CF3, -OCOR, -SR, -NR2 or PR2, wherein R is an hydrocarbon substituent; and p is 0-3. Furthermore, a catalyst system for olefin polymerization based on the above bridged metallocene compounds and the ligands for their preparation are disclosed.
