Abstract
A polyolefin blend including a propylene-based polyolefin-metal salt that is a reaction product of a propylene-containing polymer and a first organic monomer including a hydrophilic moiety that is at least partially neutralized with a metal ion, and an ethylene-based polyolefin-metal salt that is a reaction product of an ethylene-containing polymer and a second organic monomer including a hydrophilic moiety that is at least partially neutralized with a metal ion. Optionally, the blend includes a copolymer of ethylene and an alpha-olefin, and optionally one or more diene(s); a thermoplastic elastomer, such as an olefinic copolymer with styrene; a copolymer of ethylene, at least one alpha-olefin, and/or a monomer with a hydrophilic moiety. Also included are methods of preparing such blends, as well as the resultant articles.
