The present disclosure provides copolymers useful in medical devices. For example, the disclosure provides copolymers comprising the polymerization product ester block, ether blocks and diisocyanates. In certain embodiments, the disclosure provides a medical copolymer for implantation comprising ester blocks and ether blocks, wherein: the ester blocks comprise a negative free energy transfer and the ether blocks comprise a positive free energy transfer, the ether and ester blocks are less than 1/10 the length of said copolymer, and, the blocks are distributed such that no domain of contiguous blocks possessing the same polarity of free energy transfer are less than ⅓ of the molecular weight of the copolymer. The disclosure further provides methods of making the aforementioned polymers, and medical devices comprising the polymers.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

An elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are bonded through joint holes penetrating an elastic film at a plurality of sheet joined portions arranged at intervals is included. Joined portion groups in the stretchable region are in a relationship of intersecting a stretchable direction line at respective positions in an orthogonal direction or in a relationship of not intersecting the stretchable direction line at a separation width of 0.5 mm or less in the orthogonal direction of the stretchable direction line. The joined portion groups are in a relationship of not intersecting an oblique line at a predetermined separation width in the orthogonal direction in an oblique line group of oblique lines q in the orthogonal direction intersecting the stretchable direction line within an angle range γ of 45 degrees or less.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and/or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability. These products include human and other footwear, both soles and uppers, as well as orthotics; athletic, occupational and medical equipment and apparel; padding or cushioning, such as for equipment or tool handles, as well as furniture; balls; tires; and any other structural or support elements in a mechanical, architectural, or any other product.

the absorbent sheet for pets which can suppress the outflow of a functional material is provided. An absorbent sheet (10) for pets includes a topsheet (12), a backsheet (14), an absorber (20) provided between the topsheet and the backsheet, a functional (40) material, and a recess (50)that is recessed in a direction from the topsheet toward the backsheet. The functional material (40) is provided at a position of the recess (50).

A method of constructing a building comprising the steps of attaching a first panel to a second panel. The first panel is one of a single plenum panel and a multi-plenum panel and the second panel is one of a single plenum panel and a multi-plenum panel.

A laminate comprises a wicking fabric and a polymeric film adhered to both sides of the wicking fabric, wherein the wicking fabric comprises a plurality of holes, the polymeric films on both sides of the wicking fabric are fused together at each hole, and the laminate functions as an air barrier when measured in accordance with ASTM E2178-13, and allows the passage of liquid water as per ASTM E2273-18.

A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.

An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

Provided is an electric connector, which is to be arranged between a connection terminal of a first device and a connection terminal of a second device, and is configured to electrically connect the connection terminal of the first device and the connection terminal of the second device to each other, the electric connector including a composite, the composite including: an elastic body having a plurality of through holes that penetrate therethrough in a thickness direction; and a conductive member, which is joined to an inner wall of each of the through holes, and is configured to electrically connect the connection terminal of the first device and the connection terminal of the second device to each other, wherein at least a part of a vicinity of at least one of distal ends of the conductive member is hollow.
