ABSTRACT:
An article formed from a polyolefin resin blend reaction product that includes at least one propylene-based polyolefin-metal salt and at least one property-modifying agent. Optionally, the article includes a polyethylene-based polyolefin-metal salt, thermoplastic elastomer, such as a hydrogenated styrene-butadiene random copolymer or any other styrenic block copolymer, semi-crystalline polyolefin component, or the like, or combinations thereof. Such articles have enhanced scratch and mar resistance while still retaining acceptable impact toughness. Methods of preparing articles and the blends used to form such articles are also part of the invention.
