Bimodal polyethylene resins and pipes produced therefrom
Disclosed herein are ethylene-based polymers generally characterized by a density of at least 0.94 g/cm3, a high load melt index from 4 to 20 g/10 min, a zero-shear viscosity at 190° C. from 20,000 to 400,000 kPa-sec, and a relaxation time at 190° C. from 225 to 3000 sec. These ethylene polymers can...

| description | Disclosed herein are ethylene-based polymers generally characterized by a density of at least 0.94 g/cm3, a high load melt index from 4 to 20 g/10 min, a zero-shear viscosity at 190° C. from 20,000 to 400,000 kPa-sec, and a relaxation time at 190° C. from 225 to 3000 sec. These ethylene polymers can be produced by peroxide-treating a broad molecular weight distribution Ziegler-catalyzed resin, and can be used in large diameter, thick wall pipes and other end-use applications. |
