    Abstract: Disclosed are compositions comprising at least one polyolefin, a hindered phenol, and a phenyl phosphite; wherein the overall concentration of the hindered phenol and phenyl phosphite is within a range from 10 ppm to 5000 ppm in the polyolefin, and wherein the amount of the hindered phenol is less than the phenyl phosphite. Also disclosed herein are compositions comprising at least one polypropylene, a neutralizer, a hindered phenol, and a phenyl phosphite; wherein the overall concentration of the hindered phenol and phenyl phosphite is within a range from 1000 ppm to 5000 ppm in the polyolefin, and wherein the amount of the hindered phenol is from 200 to 2000 ppm less than the phenyl phosphite.

    Abstract: A bicomponent fiber comprising a sheath, where the sheath includes a propylene-based elastomer, said propylene-based elastomer including propylene-derived units and from about 3.0 to about 15 wt % alpha-olefin-derived units other than propylene-derived units, based upon the entire weight of the copolymer, said propylene-based elastomer having a triad tacticity of greater than 75%, and a heat of fusion, as determined by DSC, of less than 75 J/g; and a core, where the melt temperature of the core, as determined by DSC, is at least 5% greater than the melt temperature of the sheath.
