Abstract
This invention relates to an in-reactor polymer blend comprising: (a) a first ethylene-containing polymer having a density of greater than 0.90 g/cm3 and a Mw of more than 20,000 g/mol and (b) a second ethylene-containing polymer having a density of less than 0.90 g/cm3 wherein the polymer blend has a Tm of at least 90° C. (DSC second melt), a density of less than 0.92 g/cm3, and the densities of the first and second polymers differ by at least 1%.
