Abstract

Disclosed herein are broad molecular weight distribution olefin polymers having densities in the 0.895 to 0.930 g/cm3 range, and with improved impact and tear resistance. These polymers can have a ratio of Mw/Mn in the 8 to 35 range, a high load melt index in the 4 to 50 range, less than about 0.008 LCB per 1000 total carbon atoms, and a reverse comonomer distribution.
