Abstract: An adhesive composition, a method of making the adhesive composition, and an article that contains the adhesive composition are provided. The adhesive composition contains a polymeric material that includes a monomeric unit derived from a polyether (meth)acrylamide macromer having a polyether group comprising at least 50 mole percent propylene oxide based on total moles of alkylene oxide in the polyether group. The article includes a layer of the adhesive composition positioned next to a substrate. The articles can be, for example, an adhesive tape or can be part of another article such as, for example, an electronic device that is impact resistant and/or flexible.

Abstract: Described herein is an adhesive composite composition. The composition comprises: a plurality of polymeric microspheres dispersed within a (meth)acrylate-based matrix, wherein the polymeric microspheres are derived from 20 to 99 wt % of a (meth)acrylate monomer having a Tg above room temperature and at least 1 wt % of a polar (meth)acrylate monomer; and the (meth)acrylate-based matrix is derived from a C1 to C20 (meth)acrylate ester monomer and at least 1 wt % of a (meth)acrylate macromer. In some embodiments, these composite adhesives show good impact resistance and good shear. In one embodiment, an ionic liquid is added to the adhesive composite composition to aid in electro-debonding of articles.

Abstract: Curable and cured compositions as well as articles containing the curable or cured compositions are provided. The cured compositions are typically a semi-structural or structural adhesive. Advantageously, the cured compositions can be removed (e.g., de-bonded) from the various surfaces of the articles after the useful lifetime of the articles, to correct misplacement of a part during manufacturing, or to repair the electronic device. The separation step occurs using a direct current electric potential across the cured composition.

Abstract: Pressure-sensitive adhesive compositions that contain polymer microspheres with an average particle size of 20 μm to 100 μm, the polymer microspheres synthesized using the disclosed suspension polymerization techniques and include at least three structural isomers of a secondary (meth)acrylate of Formula (I), where R1 and R2 are each independently H or a C1 to C10 saturated linear alkyl group, the sum of the number of carbons in R1 and R2 is 7 to 18, inclusive, and R3 is H or CH3. The disclosed pressure-sensitive adhesive compositions may be used in masking articles to provide holding power to, clean paint-lines on, low surface energy adhesion to, and excellent damage-free removal from painted surfaces.

Abstract: Curable and cured compositions as well as articles that contain the curable or cured compositions are provided. The curable composition comprises (a) a (meth)acrylic-based multiblock copolymer, (b) a random (meth)acylate copolymer comprising a monomeric unit having a pendant poly(alkylene oxide) group, wherein the monomeric unit having the pendant poly(alkylene oxide) group has a number average molecular weight of at least 300 Daltons, (c) an epoxy resin, and (d) a cationic photoinitiator. Articles containing the curable composition can be die-cut and can retain their dimensions with minimal oozing when stored under ambient conditions.

Abstract: An adhesive composition containing the polymer derived from the polyether-containing monomer is provided. More specifically, the polyether-containing macromer having a urea (—NH—(C═O)—NH—) or carbamate (—NH—(C═O)—O—) linkage between the polyether group and a (meth)acryloyl group. The adhesive composition is typically a pressure-sensitive adhesive. Additionally, an article is provided that contains the adhesive composition positioned adjacent to a substrate. The articles can be, for example, an adhesive tape or can be part of another article that is flexible and foldable such as, for example, an electronic device that is flexible and/or foldable. The adhesive compositions can be tolerant of high temperature and high humidity conditions (e.g., 65 degrees Celsius and 90 percent relative humidity for 14 days).
