    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： A polyolefin blend is presented having a propylene containing polymer as a base component, a portion of which is functionalized with a hydrophilic moiety; a toughening component of polymer selected from the group consisting of(A) a copolymer of ethylene and an alpha olefin and (B) a terpolymer of ethylene, an alpha olefin and a diene; an interfacial modifier in the form of an elastomeric block copolymer; and a filler. The functionalized portion of the propylene containing polymer is present in an amount sufficient to ensure dispersion of the filler within the semi-cystalline portion of the blend; the toughening agent is present in an amount sufficient to enhance low temperature impact properties of the blend but less than about 40 weight percent, the interfacial modifier is present in an amount sufficient to assist in adhesion between the polymer components of the blend but less than about 30 weight percent, and the filler is present in an amount sufficient to enhance blend strength and hardness but less than about 40 weight percent. Also included is an article of manufacture containing the polyolefin blend described and a method for making such an article of manufacture by molding the described polyolefin lend into the configuration and shape of the article of manufacture, and the use of such articles as automobile components.
