Supported olefin polymerization catalyst |
| abstract |
(A) transition metal compounds, (b) (i) aluminoxanes or (ii) activators comprising Group IIIA metals or metalloid compounds, and (c) inorganic metal oxides, inorganic metal halides or polymeric substances or mixtures thereof. A supported catalyst system is provided, characterized in that the support material is pretreated with a source of transition metal atoms. The preferred transition metal compound is a metallocene and the source of the transition metal atom is typically a metal salt of iron or copper. Supported catalyst systems exhibit improved activity and can also reduce deposits during the gas phase fluidized bed process. |
