Abstract: Provided is an apparatus for dispensing a composition that includes a barrel having an inlet and outlet, an extrusion screw, and a drive mechanism operatively coupled to the extrusion screw. The extrusion screw includes a shaft having a shank end for connection to the drive mechanism and a distal end opposite the shank end. A first helical flight extends around a first section of the shaft, and a second helical flight extends around a second section of the shaft. The second section is located distal to the first section and the first helical flight has a nominal outer radius less than that of the second helical flight, and optionally the first helical flight has a pitch shorter than that of the first helical flight.

Abstract: Methods of bonding a pressure-sensitive adhesive to a substrate are provided. The methods include heating a styrenic block copolymer composition to provide an adhesive melt composition, wherein the styrenic block copolymer composition contains a hard segment block with a glass transition temperature of from 90°C to 220°C; masticating the adhesive melt composition; delivering the adhesive melt composition onto the substrate at a temperature that exceeds the glass transition temperature of the hard segment block by from 20°C to 150°C; and cooling the adhesive melt composition to obtain a bonded pressure-sensitive adhesive. Optionally, the substrate can be a non-film substrate, or the styrenic block copolymer composition can be provided in a core-sheath filament that includes a styrenic block copolymer core and a sheath that is non-tacky at ambient temperature.

Abstract: A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.

Abstract: Described are adhesive compositions containing a block copolymer component that includes a midblock segment and a plurality of end block segments, each end block segment comprising polystyrene, a (meth)acrylic functional additive having a glass transition temperature of from 50°C to 160°C, a first tackifier compatible with the midblock segment and containing a hydrocarbon, and a second tackifier compatible with the end block segments and containing a polyphenylene ether. These compositions are useful in providing pressure-sensitive adhesives that are melt processible, display a high temperature resistance, and effectively bond to low surface energy substrates.

Abstract: Various embodiments of lightguides and illumination systems that include lightguides are disclosed. In one or more embodiments, a lightguide can include first and second light extractors (330,340) that extract light that would otherwise be confined and propagate within the lightguide along the length of the lightguide primarily by total internal reflection. The first and second light extractors can form respective first and second patterns along a length of the lightguide. Light extracted by the first light extractors can exit the lightguide primarily along a first direction (306). Light extracted by the second light extractors can exit the lightguide primarily along a second direction (308) different from the first direction. A brightness of the total light extracted by the first light extractors can be larger than a brightness of the total light extracted by the second light extractors.
