ABSTRACT:
Polymeric compositions and methods of making and using such compositions are provided. The compositions incorporate at least one component that is a polymer including propylene-derived units and at least one component that is a styrenic block copolymer. The polymeric compositions are found to have desirable elastomeric properties while at the same time exhibiting beneficial processability characteristics. The unique combination of processability and performance attributes result in the polymeric compositions useful in a variety of applications such as films, fibers, woven and non-woven fabrics, sheets, molded objects, extruded forms, thermoformed objects, and all products made from such application materials.
