ABSTRACT:
Catalyst compositions comprising metallocene complexes having Lewis base functionality may be used for the preparation of polyolefins. Preferred complexes are zirconium complexes in which the Lewis base functionality is provided by ether or thioether groups.
The catalyst compositions may be supported on inorganic supports or on supports having polymerisation activity eg Ziegler catalysts.
