Abstract: The invention relates to thermoplastic polyolefin compositions having enhanced surface durability and products thereof which include a thermoplastic polyolefin base component at least one radiation-crosslinkable component present in an amount sufficient to enhance the surface durability of the thermoplastic polyolefin component when radiation-cured and at least one photoinitiator present in an amount sufficient to initiate crosslinking of the radiation-crosslinkable component upon exposure of the thermoplastic polyolefin composition to radiation.

Abstract: Thermoplastic polymer blends and formed articles made thereof which exhibit superior physical properties such as a combination of excellent scratch resistance, rigidity and impact toughness. The thermoplastic polyolefin blend includes from about 40 percent to about 80 percent of a base component of propylene-containing polymer; from about 5 percent to about 30 percent of a toughening component; and from about 3 percent to about 40 percent of a thermoplastic elastomer, preferably of a high styrene containing block or random copolymer. A preferred thermoplastic polyolefin blend includes between about 50 percent to about 70 percent of the base component; between about 10 percent to about 20 percent of the toughening component; and between about 5 percent to about 20 percent of the styrene block copolymer. Advantageously, the thermoplastic elastomer has greater than 50 percent by weight styrene monomer.

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.

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.
