Abstract: A crosslinkable composition, a crosslinked composition formed upon exposure of the crosslinkable composition to ultraviolet radiation or ionizing radiation, articles containing these compositions, and methods of making the articles are described. The crosslinkable compositions contain two different (meth)acrylate copolymers and can be applied to a substrate using an extrusion process. While being extruded, the crosslinkable compositions advantageously are resistant to crosslinking and/or increased molecular weights. The crosslinked compositions can function as adhesive compositions that are particularly well suited for use in electronic devices.

Abstract: A machine and method for corrugating a metal foil strip utilizes an enclosure defining a chamber and a controllable heat source for heating the chamber. The chamber may optionally include at least one gas that is also heated by the heat source. At least one tool set received in the chamber forms corrugations in the metal foil strip. Foil entry feeder elements supply and guide the metal foil strip from outside the chamber into the chamber and to the tool set. A drive for the tool set is mounted outside the chamber and coupled to the tool set to actuate the tool set. Foil exit delivery elements guide the strip from the tool set and out of the chamber. Where required to prevent oxidation of the foil strip, a source supplying an inert gas to the chamber at a controlled rate is used.
