    摘要： 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. The invention further relates to methods of providing a cured thermoplastic polyolefin composition having enhanced surface durability by preparing a mixture having a thermoplastic polyolefin base component, at least one radiation-crosslinkable component in an amount sufficient to enhance the surface durability of the polyolefin when radiation cured, and at least one photoinitiator each in an amount sufficient to facilitate crosslinking of the radiation-crosslinkable component when a surface of the thermoplastic polyolefin composition is exposed to radiation, and then exposing the thermoplastic polyolefin composition to radiation in an amount sufficient to crosslink the radiation-crosslinkable component thereby providing a thermoplastic polyolefin composition having enhanced surface durability.

    摘要： Molded articles of thermoplastic polyolefin blends having improved resistance to fluids such as petroleum fuels after being painted with flexible coatings such as polyurethane paints and the like are disclosed. These blends include a crystalline or semi-crystalline polyolefin such as polyethylene, polypropylene, or a copolymer of ethylene and a C3 to C10 olefin, and a multimodal elastomer of sequentially polymerized ethylene-&agr;-olefin monomers. The substantially crystalline polyolefin is present in an amount of 30 to 98 weight percent, while the multimodal elastomer, which is substantially amorphous, is present in an amount of about 2 to 70 weight percent. The blends may contain additional polymeric components, fillers and the like. In addition to increased paint adherence, higher weld line strength, low temperature ductility, and processability can be achieved.

    摘要： 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.
