    摘要: An olefin polymerization process comprises gas-phase polymerization of at least one olefin monomer in more than one polymerization zones using a high activity Ziegler-Natta catalyst system comprising a solid, magnesium-supported, titanium-containing component and an aluminum alkyl component comprising introducing the titanium-containing component and an aluminum alkyl component into the first polymerization zone and then introducing additional aluminum alkyl component into a subsequent polymerization zone without added titanium-containing component.
