Supported olefin polymerization catalyst |
| abstract |
Supported catalyst systems are provided comprising (a) a transition metal compound, (b) a non aluminoxane activator comprising, and (c) a support material comprising an inorganic metal oxide, inorganic metal halide or polymeric material or mixtures thereof characterised in that the support material has been pretreated with an SO 4 containing compound. The preferred transition metal compounds are metallocenes and the SO 4 containing compound is typically sulphuric acid. The supported catalyst systems show improved activity and also may reduce fouling in gas phase fluidised bed processes. |
