Abstract: Ethylene-based polymers having a density of 0.952 to 0.968 g/cm3, a ratio of HLMI/MI from 185 to 550, an IB parameter from 1.46 to 1.80, a tan ? at 0.1 sec?1 from 1.05 to 1.75 degrees, and a slope of a plot of viscosity versus shear rate at 100 sec?1 from 0.18 to 0.28 are described, with low melt flow versions having a HLMI from 10 to 30 g/10 min and a Mw from 250,000 to 450,000 g/mol, and high melt flow versions having a HLMI from 30 to 55 g/10 min and a Mw from 200,000 to 300,000 g/mol. These polymers have the processability of chromium-based resins, but with improved stress crack resistance and topload strength for bottles and other blow molded products.
