Abstract
A catalyst prepared by firstly depositing a large amount of aluminoxane on a particulate support, then depositing a small amount of monocyclopentadienyl zirconium trihalide on the support. The catalyst is active for the polymerization of ethylene, optionally with a minor amount of other alpha olefins such as butene or hexene, particularly in a gas phase process.
