Abstract
A polyolefin blend is presented that includes a base component of a propylene-containing-polymer, such as polypropylene, a propylene-based polyolefin-metal salt, and an ethylene-based polyolefin-metal salt. Optionally, the blend includes a copolymer of ethylene and an alpha-olefin; a terpolymer of ethylene, alpha-olefin, and a diene; a thermoplastic elastomer, such as an olefinic copolymer with styrene; and/or a copolymer of ethylene, at least one alpha-olefin, and a monomer with a hydrophilic moiety. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.
