DIMERS AND TETRAMERS OF CYCLOPENTDIENYL GROUP 6B-ALPHA-OLEFIN POLYMERIZATION CATALYSTS AND METHOD FOR OLEFIN POLYMERIZATION. |
| abstract |
The invention relates to a catalyst system for the homopolymerization and copolymerization of alpha-olefins having 2 to 8 carbon atoms, said catalyst system containing a metal compound of group 6b based on dimeric or tetrameric cyclopentadienyl in which the metal is present. an oxidation state of 2+, the group 6b metal being placed on an inorganic support. Said catalyst system may also contain a Group 2 or 3 metal alkyl cocatalyst. |
