A web material which exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having at least two visually distinct regions of the same material composition. The first region undergoes a molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the web material is subjected to an applied elongation in a direction substantially parallel to the axis of elongation.

Web materials exhibiting elastic-like behavior

A unitary disposable garment, such as disposable training pants, having a high degree of stretch in the cross-machine direction and fitting a broad range of wearer sizes. The unitary disposable garment is manufactured from a chassis and has a waist opening, two leg openings and a pair of side seams which join the front portion of the chassis to the rear portion of the chassis. The unitary disposable garment preferably has an absorbent assembly, i.e. an absorbent insert, secured to the inner layer of the chassis. The chassis from which the unitary disposable garment is manufactured, has four elasticized ear flaps; each ear flap is elasticized by securing an elastomeric element thereto and mechanically stretching the ear flap and the elastomeric element such that the ear flap is elastically extensible in the direction of initial stretching. The front portion of the chassis is then joined to the rear portion of the chassis on each side of the disposable garment by a seam.

A composite elastic material including at least one reversibly necked material and at least one elastic sheet joined at least at two locations in which the reversibly necked material is formed from a neckable material which has been treated so that, upon application of a force to extend the necked material to its pre-necked dimensions, the material returns generally to its necked dimensions upon termination of the force. Also disclosed is a process for making a composite elastic material by joining a reversibly necked material to an elastic sheet at least at two locations.

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. The compositions of the present invention preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin.

The lithographic template is formed having a substrate, an optional etch stop layer formed on a surface of the substrate, and a patterning layer formed on a surface of the etch stop layer. The template is used in the fabrication of a semiconductor device for affecting a pattern in the device by positioning the template in close proximity to the semiconductor device having a radiation sensitive material formed thereon and applying a pressure to cause the radiation sensitive material to flow into the relief image present on the template. Radiation is then applied through the template so as to further cure portions of the radiation sensitive material and further define the pattern in the radiation sensitive material. The template is then removed to complete fabrication of the semiconductor device.

Microtextured elastomeric laminates comprising at least one elastomeric layer and at least one thin skin layer is preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate to recover.

Elastomeric laminates with microtextured skin layers

Microtextured elastomeric laminates comprising at least one elastomeric layer and at least one thin skin layer is preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers in predetermined regions of the laminate and then allowing the laminate to recover in these regions.

The present invention provides a release coated film, an adhesive tape comprising a release coated film, and processes for preparing the same The fluoropolymer release layer comprises a graft copolymer of (i) a base polymer containing polymerized units derived from monomers having terminal olefinic double bonds, and (ii) a moiety comprising a fluoroaliphatic group The film may be coextruded and may subsequently be oriented in at least one direction Alternately, the release coating can be extrusion coated onto a backing and may be subsequently oriented if the backing is orientable Adhesives may be coated onto the release coated films either before or after orientation, or they may be coextruded along with the release coating and/or backing

Extrudable release coating

A die apparatus, a method of using the die apparatus to produce co-extruded polymeric articles, and co-extruded polymeric articles produced using the die apparatus and method are disclosed. The die apparatus includes a hollow vane configured to extrude a material into a chamber within the die, thereby producing a co-extruded web. The co-extruded web has a plurality of distinct, discontinuous phases in the cross-web direction, the phases having a uniform width as shown by a coefficient of variation of less than 8 percent for any three consecutive phases. The phases are substantially continuous down-web and are surrounded by a matrix having two or more layers.
