Polymers having a broad molecular distribution, excellent toughness and improved processability are disclosed. <??>The polymers may be prepared by use of a single metallocene catalyst system in a single reactor preferably operating continuously under a single set of reaction conditions. <??>The polymers of density typically 0.85 - 0.95 are defined in particular by their melt strength and long chain branching characteristics and are particularly suitable for use in low density film applications.
