Abstract: Disclosed herein are ethylene-based polymers having a density greater than 0.945 g/cm3, a high load melt index less than 25 g/10 min, a peak molecular weight ranging from 52,000 to 132,000 g/mol, and an environmental stress crack resistance of at least 250 hours. These polymers have the processability of chromium-based resins, but with improved impact strength and stress crack resistance, and can be used in large-part blow molding applications.

Abstract: Disclosed herein are polymerization processes for the production of olefin polymers. These polymerization processes use a catalyst system containing three metallocene components, often resulting in polymers having a reverse comonomer distribution and a broad and non-bimodal molecular weight distribution.

Abstract: Disclosed herein are polymerization processes for the production of olefin polymers. These polymerization processes can employ a catalyst system containing two or three metallocene components, resulting in ethylene-based copolymers that can have a medium density and improved stress crack resistance.
