A Bridge with a metallocene ligand useful as an intermediate in the synthesis of metallocene Catalyst for olefin polymerization and Process for polymerization of Olefins

摘要

A metallocene of formula (i), (zr1m) where n is a divalent Group that acts as a bridge between CP and CP is a Heterocyclic Group, ciclopentadienilo formula (ii) or (ii)Where one of the X or y is a Single Bond, the other being a hetero Atom; R3 and R3 is Hydrogen, halogen or a Hydrocarbon radical,Optionally containing heteroatoms; R4 is Halogen or a Hydrocarbon radical, optionally containing heteroatoms; the group is underivado of ciclopentadienilo or is equal to M is you, COP.ZR or HF; M is 1 or 2; n ranges between 0 and 4, R is 0 OR 1; and P and q ranges from 0 to 3; is included between 0 and 4.In addition, reveal these metallocenes catalysts containing Systems, which are useful in the polymerization of olefins.
