Abstract

A polyolefin resin blend is presented that includes a base component of a semi-crystalline polyolefin component, a propylene-based polyolefin-metal salt, and a styrenic block ionomer. Optionally, the blend includes a thermoplastic elastomer, such as a hydrogenated styrene-butadiene random copolymer. Such blends have enhanced scratch and mar resistance while still retaining acceptable impact toughness. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.
