Abstract
An ionomeric nanocomposite that includes a base component of a propylene-based polyolefin-metal salt component and a nanostructured material. Optionally, the blend further contains a polymeric component including an ethylene ionomer, a styrenic block ionomer, a hydrogenated styrene-butadiene random copolymer, or a combination thereof. Such ionomeric nanocomposites have increased scratch and mar resistance while still retaining clarity and thermal stability. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.
