Abstract
Disclosed herein are polymerization processes for the production of olefin polymers. These polymerization processes use a catalyst system containing three metallocene components, often resulting in polymers having a reverse comonomer distribution and a broad and non-bimodal molecular weight distribution.

An olefin polymer having a melt index in a range from about 0.005 to about 10 g/10 min, a ratio of HLMI/MI in a range from about 50 to about 500, a density in a range from about 0.915 g/cm3 to about 0.965 g/cm3, a reverse comonomer distribution, and a non-bimodal molecular weight distribution.
An olefin polymer having a melt index in a range from about 0.005 to about 10 g/10 min, a ratio of HLMI/MI in a range from about 50 to about 500, a density in a range from about 0.915 g/cm3 to about 0.965 g/cm3, a non-bimodal molecular weight distribution, and less than about 0.008 long chain branches (LCB) per 1000 total carbon atoms.
