摘要： Disclosed is a multimodal, high density, homopolyethylene barrier resin. The resin is preferably made by a multistage process. The process comprises a first stage in which ethylene is homopolymerized in the presence of a Ziegler-Natta catalyst, organoaluminum cocatalyst, alkoxysilane modifier, and hydrogen. The reaction mixture from the first stage is devolatilized to remove all or substantially all of the hydrogen. The polymerization continues in a second stage wherein ethylene is added to the devolatilized reaction mixture to produce the barrier resin. The barrier resin provides films with improved barrier properties.
