摘要： 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.

摘要： A crosslinkable composition, a crosslinked composition formed upon exposure of the crosslinkable composition to ultraviolet radiation or ionizing radiation, articles containing these crosslinkable or crosslinked compositions, and methods of making the articles are described. The crosslinkable compositions contain two different (meth)acrylate polymers and can be applied to a substrate using an extrusion process. While being extruded, the crosslinkable compositions advantageously are resistant to crosslinking and/or significantly increasing in molecular weight. The crosslinked compositions can function as either a pressure-sensitive adhesive composition or a heat bondable adhesive composition and are particularly well suited for use in electronic devices.

摘要： An adhesive composition is described comprising a polyisobutylene polymer component; and up to 30 wt.-% of at least one aliphatic multifunctional component comprising at least two ethylenically unsaturated groups selected from (meth)acryl or vinyl ether. The monomer comprises a hydrocarbon moiety with greater than 12 contiguous carbon atoms. When the hydrocarbon moiety is branched, the hydrocarbon moiety comprises side chains with at least two carbon atoms. The aliphatic multifunctional component is sufficiently compatible such that crosslinked adhesive composition at a thickness of 20 microns has a haze of less than 3%. Also described are adhesive articles.

摘要： Compositions are described comprising at least 20 wt. % of block copolymer comprising polyvinyl aromatic end blocks and a polyisoprene midblock and at least one ethylenically unsaturated monomer comprising one or more groups selected from (meth)acryl or vinyl ether. In one embodiment, the monomer has a Log P according to Moriguchi's method of at least 2.2. In another embodiment, the monomer is a multifunctional aromatic ethylenically unsaturated monomer. The composition is typically a (e.g. pressure sensitive) adhesive. Also described are methods of making an article, adhesive articles, and methods of bonding.

摘要： The present invention is an assembly layer for a flexible device. Within a temperature range of between about −30° C. to about 90° C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed about 2 MPa, a shear creep compliance (J) of at least about 6×10−6 1/Pa measured at 5 seconds with an applied shear stress between about 50 kPa and about 500 kPa, and a strain recovery of at least about 50% at at least one point of applied shear stress within the range of about 5 kPa to about 500 kPa within about 1 minute after removing the applied shear stress. The assembly layer includes at least one of a polyisoprene, a polybutadiene, an olefin block copolymer, a polyisobutylene, and high alkyl polyolefin.

摘要： A composition is described comprising a styrene-isobutylene block copolymer; and at least one ethylenically unsaturated monomer. After curing the composition comprises polymerized units of the ethylenically unsaturated monomer. In some embodiments the ethylenically unsaturated groups are selected from (meth)acryl or vinyl ether. The composition is suitable for use as a (e.g. pressure sensitive) adhesive. Articles, methods of making an article, and methods of bonding are also described.
