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/cmand 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/cm, wherein the polymer blend has a Tm of at least 90° C. (DSC second melt), a density of less than 0.92 g/cm, and the densities of the first and second polymers differ by at least 1%. Specifically this invention relates to an in-reactor polymer blend comprising: (a) a first ethylene polymer comprising 90 to 100 wt % ethylene and from 0 to less than 10 wt % comonomer, said first ethylene polymer component having density of greater than 0.920 g/cm, an Mw of 20,000 g/mol or more; and (b) a second ethylene polymer comprising from 70 to 90 wt % ethylene and 30 to 10 wt % comonomer, said second ethylene polymer having a density of 0.910 g/cmor less, wherein the polymer blend has:
