Abstract: Absorbent articles are described comprising a first absorbent layer comprising a polymeric foam. In one embodiment, the polyurethane foam comprises the reaction product of a polymeric polyisocyanate component having an equivalent weight of no greater than 250 g/equivalent; and a polyol component. The polyol component comprises one or more polyether polyols such that the polyol component comprises an average equivalent weight ranging from 500 to 2000 g/equivalent; an ethylene oxide content ranging from 15-30 wt.-%; a secondary hydroxyl content of at least 55 wt.-% and less than 80 wt.-% of the total hydroxyl content of the polyol component; and less than 5 wt-% water. Also described are various composites comprising the polyurethane foam described herein in combination with another substrate such as a second absorbent layer, a fluid impervious backsheet, and/or a fluid pervious topsheet.

Abstract: Light fixtures (100, 200, 400, 500, 600, 700) are provided, including a lighting element (10, 20, 40, 50, 60, 70), an oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72) disposed adjacent to or connected to the lighting element, and a control mechanism (14, 24, 44, 64, 74). The control mechanism is in electrical communication with the lighting element (10, 20, 40, 50, 60, 70) and controls an energy output of the lighting element and a temperature of the oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72). Typically, when the control mechanism changes the temperature of the oriented crosslinked semi-crystalline polymer, the shape of the polymer changes. A method of making a light fixture (100, 200, 400, 500, 600, 700) is also provided. The method includes providing a lighting element (10, 20, 40, 50, 60, 70), forming a crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72), and disposing the crosslinked semi-crystalline polymer adjacent to the lighting element (10, 20, 40, 50, 60, 70) or connecting the crosslinked semi-crystalline polymer to the lighting element. The method further includes electrically connecting a control mechanism (14, 24, 44, 64, 74) with the lighting element.

The second layer is interlocked with the undercut features, the third layer is adhered to the adhesive, and the second layer is disposed between the first layer and the third layer. A method is also provided including (a) depositing a polyolefin resin into a mold cavity to form a first layer including undercut features; (b) demolding the first layer from the mold cavity at a rate of at least 150 millimeters per minute; (c) applying a curable adhesive to the undercut features to form a second layer attached to the first layer; and (d) attaching a third layer including a substrate to the second layer.

Abstract: A dispensing device (100) is configured to dispense polymer fasteners from a strand of oriented shape memory polymer configured to expand laterally and contract longitudinally when heated. The dispensing device includes a strand dispenser (101) arranged to dispense the strand. A strand metering mechanism (102) is operable in conjunction with the strand dispenser to dispense a predetermined length of the strand. A cutting mechanism (103) is configured to cut the strand to form a polymer fastener of predetermined length.
