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.
Claims23
An article formed from a polyolefin blend comprising a propylene-based polyolefin-metal salt that is a reaction product of a propylene-containing polymer consisting essentially of at least one propylene homopolymer or one or more propylene-based copolymers of propylene and no more than about 20 mole percent ethylene or other alpha-olefins, which polymer is functionalized with a first hydrophilic moiety comprising at least one carbonyl group and at least one metal ion present in an amount sufficient to at least partially neutralize the first hydrophilic moiety, and a property-modifying agent.
