Catalysts containing metallocenes with arylsubstituted indenyl derivatives as ligands, process and intermediates for the preparation of these metallocenes and their use

(57) A summary and the purpose The present invention offers the metallocene which contained the アリール substitution in デニル derivative as a ligand. Composition The very effective catalyst system for polymerization of an olefin or copolymerization contains the metallocene shown by the co-catalyst (preferably aluminoxane or supported aluminoxane) and the formula I. Among the above-mentioned formula, in a desirable mode, M is Zr or Hf, R and R are halogen or アリール, R is アルキル, and R*R is アルキル or a hydrogen atom, and R is a bridge by Al (replaced) Killen or a hetero atom. Use of metallocene (especially zirconocene) will obtain the polymer which has a very high molecular weight, a very high stereo タクチ city, and the very high melting point in high catalytic activity in the high temperature requirement (50*80 °C) of industrial especially concern in the case of a pro chiral monomer. Furthermore, the affix generation to a reactor can be prevented by using a support catalyst system.
