    摘要： The invention is directed to compositions comprising an elastomer component and a propylene component, and in which the elastomer component comprises at least one ethylene/α-olefin polymer, optionally containing a diene, and the polypropylene component comprises at least one branched polypropylene. Preferably, the elastomer component has a melt tan delta between about 0.7 and about 8, as measured by parallel plate rheometer at 0.1 rad/sec, 190° C., and 15 percent strain; and the ratio of the “melt tan delta of the elastomer component” to the “melt tan delta of the propylene component” is from 0.5 to 4. The invention also provides for method of making such compositions, and to low gloss articles prepared from the same. The inventive compositions are particularly suitable for fabricating thermoformed sheeting with reduced gloss.

    摘要： The adhesion between a low surface energy (i.e., nonpolar) material, e.g., a polyolefin such as polyethylene, and a high surface energy (i.e., polar) material, e.g., a polyester, polyurethane, polycarbonate or polylactic acid, is promoted by blending with the nonpolar material typically from 15 to less than 50 wt % of a diol-based thermoplastic polyurethane (d-TPU), e.g., a polydiene diol-based TPU, based on the combined weight of the nonpolar material and the d-TPU. The promoted adhesion allows for the effective painting, printing, over-molding or HF-welding of a nonpolar substrate, e.g., a polyolefin film, with a polar coating, e.g., a paint, ink, etc. Aqueous dispersions can also be made from the blend of nonpolar material and d-TPU.

    摘要： A polyolefin-based composition showing improved weldability using high frequency (HF) includes (1) a base polymer selected from (a) a homogeneously branched, linear or substantially linear ethylene/α-olefin copolymer; (b) a homogeneously branched propylene/α-olefin copolymer; or (c) a combination thereof; and (2) at least one secondary component selected from (a) an ethylene vinyl acetate copolymer having from 5 to 40 wt % vinyl acetate; (b) an ethylene-ethyl acrylate having from 5 to 25 wt % ethyl acrylate; and (c) a combination thereof. The combination of the specified polyolefin with the specified secondary component, which is a polar polymer, makes these formulations HF weldable, with a cohesive welding failure, a weld strength for 10 mil thick film greater than 7 lb/in (1.23 N/mm) at a weld time of less than or equal to 6 seconds. The formulations may also exhibit good calendering processability and mechanical properties.
