DUAL CATALYST SYSTEM FOR PRODUCING HIGH DENSITY POLYETHYLENES WITH LONG CHAIN BRANCHING

Disclosed herein are ethylene-based polymers generally characterized by a melt index of less than 1 g/10 min, a density from 0.93 to 0.965 g/cm3, a CY-a parameter at 190 oC of less than 0.2, an average number of short chain branches per 1000 total carbon atoms of the polymer in a molecular weight ra...
