    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.

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.
