Abstract
Processing properties of polyethylene resins are improved while retaining original physical properties by incorporating less than 1.5 weight percent of high molecular weight, non-crystalline polyolefins into the polyolefin resins. The resulting compositions exhibit reduced melt viscosity at high shear rates while providing essentially unchanged finished physical properties of the polyethylene article.
