    摘要： Meltblown nonwoven compositions and processes for forming them are described herein. In one or more embodiments, the invention is directed to meltblown nonwoven fabrics having at least one elastic layer, wherein the elastic layer comprises a propylene-based polymer having an MFR greater than about 25 g/10 min. Additionally, the propylene-based polymer comprises from about 5 to about 25 wt % of one or more C2 and/or C4-C12 α-olefins and has a triad tacticity greater than about 90% and a heat of fusion less than about 75 J/g. The present invention is also directed to processes for forming meltblown nonwoven fabrics comprising forming a molten propylene-based polymer having an MFR of at least about 25 g/10 min, forming fibers comprising the propylene-based polymer, and forming an elastic nonwoven layer from the fibers.

    摘要： Crosslinked polyolefin blends, methods for their production, and articles made of the same are provided. In at least one specific embodiment, the polyolefin blends comprise a first polymer formed in a first reactor and a second polymer formed in a second reactor. The first and second polymers, as well as the resulting blend, may comprise units derived from propylene, ethylene, and a diene. The blended composition can then be compounded with one or more coagents, antioxidants, and/or other additives and crosslinked, preferably by exposure to energetic photons. The crosslinked polymers are particularly useful for making fibers, films, and nonwovens.

    摘要： Methods for making a crosslinked elastomeric composition and articles made of the same are provided. In at least one specific embodiment, an elastomeric composition comprising at least one propylene-based polymer is blended with at least one component selected from the group consisting of multifunctional acrylates, multifunctional methacrylates, functionalized polybutadiene resins, functionalized cyanurate, and allyl isocyanurate; and blended with at least one component selected from the group consisting of hindered phenols, phosphites, and hindered amines. The propylene-based polymer can include propylene derived units and one or more dienes, and have a triad tacticity of from 50% to 99% and a heat of fusion of less than 80 J/g. The blended composition can then be extruded and crosslinked. The extruded polymer can be crosslinked using electron beam radiation having an e-beam dose of about 100 KGy or less. The crosslinked polymers are particularly useful for making fibers and films.
