    摘要： Propylene-based polymer compositions are provided comprising propylene and from about 5 wt % to about 20 wt % of one or more C2 and/or C4-C12 α-olefins. The polymer compositions have a triad tacticity greater than about 90%, a heat of fusion less than about 75 J/g, and a melt flow rate (MFR) greater than or equal to about 25 g/10 min (230° C., 2.16 kg). Further, the polymer compositions are reactor grade compositions comprising a reactor blend of a first polymer and a second polymer, preferably where both of the first and second polymers are prepared using the same catalyst system. Meltspun nonwoven fabrics, such as meltblown or spunbond fabrics, comprising such polymer compositions are also provided, as well as processes for forming the nonwoven fabrics.

    摘要： Elastomeric polymer blends and processes for their production are described. Specifically, the polymer blends comprise a first polymer and a second polymer, where the first polymer comprises from about 70 wt % to about 90 wt % units derived from propylene and from about 10 wt % to about 30 wt % units derived from ethylene and/or a C4-C10 alpha-olefin, and the second polymer comprises from about 88 wt % to about 98 wt % units derived from propylene and from about 2 wt % to about 12 wt % units derived from ethylene and/or a C4-C10 alpha-olefin. The elastomeric polymer blends are further characterized by having two or more of the following properties: an overall propylene content of between about 75 wt % and about 90 wt %, a melting point between about 110° C. and about 145° C., a Vicat softening point greater than about 45° C., a tensile stress at 300% strain of less than about 500 psi (3447 kPa), as determined by a stress strain test according to ASTM D412, or an average maximum force for pellet separation of less than about 10 N in an accelerated storage stability test. The polymer blends are produced in a dual reactor process, in which the first polymer and the second polymer are prepared using differing catalyst systems.

    摘要： The invention relates to thermoplastic compositions in which (A) an isotactic polypropylene, optionally containing comonomer, with a melting point of at least 110° C. and (B) a polyamide, (A) and (B) constituting at least 70 wt %, are blended with (C) at least 2 wt % of a grafted functionalized propylene-based elastomer having isotactic crystallinity and containing at least 0.25 wt % of MAH-derived units based on the total weight of (C). Optionally (D) an ungrafted polyolefin may be added with a melting point of less than 100° C., (C) and (D) combined being at least 8 wt % and the wt % of (A), (B), (C) and (D) being calculated on the basis of the total polymer weight of the thermoplastic composition.
