Abstract:
The invention relates to a polymer, comprising ethylene and at least one alpha olefin having from 4 to 20 carbon atoms, wherein the polymer has:
a peak in a first derivative of a van Gurp Palmen (vGP) plot at a frequency of between about 0.1 rad/s and 300 rad/s at 190 °C;
a melt index ratio (MIR) greater than about 15; and
a dart impact strength of greater than about 350 g/mil.
