摘要：NOVELTY - A substituted bridged metallocene ligand is new. USE - A substituted bridged metallocene complex for homopolymerization or copolymerization of alpha-alkene, preferably ethylene or propylene with ethylene or octylene co-monomer (claimed). ADVANTAGE - The substituted bridged metallocene complex has high polymerization activity. DETAILED DESCRIPTION - A substituted bridged metallocene complex of formula (I) is new. R1, R2=1-12C (fluoro)alkyl or alkoxy or halo; and M=Ti, Zr or Hf. An INDEPENDENT CLAIM is included for preparation of substituted bridged metallocene complex (I).
