A composition is provided, which comprises an ethylene/C3-C6 alpha-olefin interpolymer, and wherein the interpolymer comprises the following properties:

Ethylene/C3-C6 alpha-olefin interpolymers with improved pellet flowability

This invention relates to polyolefin compositions. In particular, the invention pertains to elastic polymer compositions that can be more easily processed on cast film lines, extrusion lamination or coating lines due to improved resistance to draw resonance. The compositions of the present invention comprise an elastomeric polyolefin resin and a high pressure low density type resin. The preferred compositions of the present invention comprise from 88 to 99 percent elastomer or plastomer and from 1 to 12 percent by weight of a high pressure low density type resin.

Elastomeric resin compositions with improved resistance to draw resonance

The present invention relates to soft touch fibers and nonwoven fabrics made from such fibers. The fibers comprise an incompatible polymer system which leads to the soft touch quality. The fibers comprise a mixture of at least two thermoplastic polymers each having different viscosities and wherein the mixture has an interfacial tension from about 0.5 to about 20 mN/m, and wherein the mixture comprises a portion of the fiber surface. The fibers may include from 40-98 percent of a polyolefin continuous phase and from 2 to 60 weight percent of an amorphous thermoplast dispersed phase, such as polystyrene or polyamide.

Fibers formed from immiscible polymer blends

Extensible bicomponent fibers and webs particularly adapted for disposable personal care product component applications. Sheath/core configurations providing desirable feel properties for elastic embodiments when compared with conventional elastic fibers and webs are obtained with specific olefin polymer combinations and sheath configurations.

Extensible and elastic conjugate fibers and webs having a nontacky feel

Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as havingC NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.
