PROBLEM TO BE SOLVED: To provide an ethylene-based polymer which is especially useful for blending with other polymers, such as LLDPE, and exhibits increased bubble stability and output when the blends are converted into a film, especially a blown film.SOLUTION: An ethylene-based polymer has a density from about 0.9 to about 0.94 g/cm, a molecular weight distribution (Mw/Mn) from about 8 to about 30, a melt index (I2) from about 0.1 to about 50 grams per 10 minutes, a gpcBR value greater than about 1.4 as determined by a gpcBR Branching Index and a Y value less than about 2. |
