Abstract:
1. A Ziegler-Natta catalyzed ethylene alpha-olefin copolymer, further comprising: a density of between 0.900 g/cc and 0.930 g/cc; a melt index ratio (I a melt index (I a polydispersity index (Mw/Mn) of between 3.0 and 5.0; wherein the Temperature Raising Elution Fractionation (TREF) fraction distribution of the copolymer has at least 15 wt % of TREF fractions below an elution temperature of 35° C.; and wherein the copolymer is produced by reacting ethylene and an alpha-olefin comonomer in the presence of a titanium-based Ziegler-Natta catalyst in a gas-phase process at reaction temperatures in the range of about 50° C. to about 100° C.
