    摘要: Provided are crosslinkable propylene-based copolymers, methods for making the same, elastomeric compositions including the same, and articles made therefrom, e.g., films and fibers. Exemplary elastomeric compositions are composed of at least one propylene-based polymer comprising propylene derived units and one or more dienes, the propylene-based polymer having a triad tacticity of from 50% to 99% and a heat of fusion of less than 80 J/g; about 0.5 wt % to about 10 wt % vinyl siloxane; and about 0.1 wt % to about 1.0 wt % peroxide. The elastomeric compositions can be extruded and crosslinked at a temperature of at least about 50° C. and a relative humidity of at least about 90% to provide a crosslinked elastomeric composition. The crosslinked elastomeric compositions are particularly useful for making fibers and films.

    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, UV sensitizers, and/or other additives and crosslinked, preferably by exposure to UV radiation and/or 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.
