Abstract:
A bimodal ethylene-based polymer, including a high density fraction (HDF) from 3.0% to 25.0%, wherein the high density fraction is measured by crystallization elution fractionation (CEF) integration at temperatures from 93° C. to 119° C., an I10/I2 ratio from 5.5 to 7.5, wherein I2 is the melt index when measured according to ASTM D 1238 at a load of 2.16 kg and temperature of 190° C. and I10 is the melt index when measured according to ASTM D 1238 at a load of 10 kg and temperature of 190° C., and a short chain branching distribution (SCBD) less than or equal to 10° C., wherein the short chain branching distribution is measured by CEF full width at half height.
