Abstract: A thermoplastic elastomer that is adherent to polar materials may be made from a dynamically vulcanized blend of propylene resin, ethylene/alpha-olefin/non-conjugated diene elastomers, and a bonding agent via a curing system containing a free radical initiator, at least one co-agent including multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures of both, where the elastomer gel content in the modified blend is at least about 97 percent. Reaction mixtures, articles made therefrom, and methods of dynamically vulcanizing are also disclosed.

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.

Abstract: A thermoplastic elastomer with increased oil resistance and decreased compression set compared to conventionally cured thermoplastic elastomers may be made from a dynamically vulcanized blend of propylene resin and ethylene/alpha-olefin/non-conjugated diene elastomers via a curing system containing a free radical initiator, a first co-agent including diene-containing polymers with a 1,2-vinyl content greater than 50% by weight, and a second co-agent including multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures of both, where the elastomer gel content in the modified blend is at least 97%.

Abstract: An ionomeric nanocomposite that includes a base component of a propylene-based polyolefin-metal salt component and a nanostructured material. Optionally, the blend further contains a polymeric component including an ethylene ionomer, a styrenic block ionomer, a hydrogenated styrene-butadiene random copolymer, or a combination thereof. Such ionomeric nanocomposites have increased scratch and mar resistance while still retaining clarity and thermal stability. Methods of preparing such blends, as well as resultant articles including such blends, are also part of the invention.

Abstract: This invention relates to polyolefin alloys that are receptive to metal plating. These compositions also have enhanced properties and are easily processed into articles by various molding methods. The blends of the invention preferably include a polyethylene component, acrylonitrile-butadiene-styrene polymer(s), and at least one styrene monoolefin copolymer. The invention also relates to articles containing such alloys, and to methods of forming such blends and articles containing the same. These blends have excellent platability and superior physical properties including enhanced stiffness and toughness.
