| 20080280517 | Compositions of Ethylene/Alpha-Olefin Multi-Block Interpolymer for Elastic Films and Laminates - 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 preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin. | 11-13-2008 |

| 20080199673 | Propylene Based Meltblown Nonwoven Layers and Composite Structures - The present invention relates to propylene-based nonwoven layers made by the meltblown process, and laminates incorporating such layers. The meltblown layers of the present invention comprise propylene copolymers characterized by having less than 50 percent crystallinity. The meltblown layers of the present invention show an improved combination of extensibility and tensile strength. The laminate structures of the present invention are characterized by a combination of low bending modulus with high peel strength. | 08-21-2008 |

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 preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin. | 09-25-2008 |
| 20100279571 | Fibers Made From Copolymers of Ethylene/A-Olefins - A fiber is obtainable from or comprises an ethylene/α-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481−1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics can be made from such fibers. | 11-04-2010 |
