摘要： A process for producing polyethylene having a broad molecular weight distribution is provided, in which ethylene and optionally a comonomer are contacted in two reactors connected in series, one reactor containing a titanium-based catalyst and the other reactor containing a vanadium-based catalyst and a halohydrocarbon promoter, or alternatively, both reactors containing a mixed metal catalyst comprising both titanium and vanadium. In the latter case, the halohydrocarbon promoter is present in only one of the reactors to activate the vanadium sites of the catalyst and deactivate the titanium sites of the catalyst simultaneously.
