Abstract
Polymeric compositions and methods of making and using such compositions are provided. The compositions incorporate a first polymeric component that is at least one high density polyethylene and a second polymeric component that is at least one polymer including propylene-derived units having a heat of fusion of less than 75 J/g wherein the propylene-derived units have an isotactic triad fraction of about 65% to about 99%. The polymeric compositions are found to have desirable environmental stress crack resistance properties and impact resistance properties. The polymeric compositions are useful in a variety of applications such as molded containers and extruded pipes.
