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: 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: An adhesive composition includes a first acrylic polymer preparable from first components and a second acrylic polymer. The first components comprising i) a branched first alkyl (meth)acrylate having from 4 to 22 carbon atoms, and ii) at least one of acrylic acid and methacrylic acid. The second acrylic polymer is preparable from second components comprising iii) at least one second alkyl (meth)acrylate having from 4 to 22 carbon atoms, iv) a (meth)acrylamide represented by the formula wherein R1 is H or methyl, and R2 and R3 each independently represents H or an alkyl group having from 1 to 8 carbon atoms, or taken together R2 and R3 may form a divalent alkylene group having from 4 to 6 carbon atoms, and v) at least one high Tg macromer having a terminal free-radically polymerizable unsaturated group, the high Tg macromer having a Tg of at least 45° C. Based on the combined total weight of the at least one first acrylic polymer and the at least one second acrylic polymer, the at least one second acrylic polymer is present at a level of from 5 to 40 percent by weight. Methods of making the adhesive composition are also disclosed.

Abstract: An article comprising a first component having a first electrically conductive surface and a second component having a second surface. An adhesive composition comprising a zwitterionic polymer is disposed between the first electrically conductive surface and second surface and joins the first component to the second component. The effort required to separate the first component from the second component, as measured by work of adhesion per surface area, is reduced by application of a DC electric potential across the adhesive composition.
