Abstract: Ethylene-based polymers having a melt index from 0.8 to 8 g/10 min, a density from 0.94 to 0.96 g/cm3, and a ratio of Mw/Mn from 6 to 20 are disclosed. These polymers can have one or more of an environmental stress crack resistance (ESCR) of at least 5,000 hr (condition A, 100% Igepal), an ESCR of at least 2,500 hr (condition A, 10% Igepal), a CY-a parameter from 0.35 to 0.53, a PSP2 value from 5 to 8.5, a tan δ at 0.1 sec−1 from 8 to 24 degrees, a Mz from 275,000 to 420,000 g/mol, an IVc from 2 to 3 dL/g, a strain hardening modulus (SHM) from 19 to 47 MPa, and/or an amount of polymer eluting between 93 and 95° C. in an ATREF profile of from 7 to 30 wt. %.
