Abstract

A process for preparing a multimodal polyethylene product with at least two different polyethylene resins includes producing a first polyethylene resin in the presence of a Ziegler-Natta catalyst in a reactor. The Ziegler-Natta catalyst used for the production of the first polyethylene resin has an average particle size (D50) of at most 15 μm. The process includes separately producing a second polyethylene resin in the presence of a Ziegler-Natta catalyst in a reactor. The process includes physically blending together the first and second polyethylene resins to produce a multimodal polyethylene product.
