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: The present invention relates to a double-sided adhesive tape used for applications including the attachment of front glass for mobile devices. A core layer of the double-sided adhesive tape is prepared by adding an acrylic elastomer free of carbon-carbon double bonds while being highly miscible with an acrylic resin to an acrylic monomer(s) and performing curing, and thus can improve the impact resistance of the final double-sided adhesive tape. Also, the core layer may take a form of foam due to the introduced filler such as glass bubbles or organic microspheres, and thus can further contribute to improving the impact resistance of the final double-sided adhesive tape.

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: A curable composition comprising 20 wt. % to 60 wt. %, optionally 30 wt. % to 58 wt. %, or optionally 40 wt. % to 55 wt. % of an acrylic block copolymer, 5 wt. % to 60 wt. %, optionally 20 wt. % to 50 wt. %, or optionally 15 wt. % to 45 wt. %, of an epoxy resin; 1 wt. % to 60 wt. %, optionally 5 wt. % to 50 wt. %, or optionally 15 wt. % to 45 wt. %, of a polyol; and 0.5 wt. % to 10 wt. %, optionally 0.75 wt. % to 8 wt. %, or optionally 1 wt. % to 5 wt. %, of a curing agent. The curable composition may be used to prepare a tape that is initially soft (i.e., low-modulus), which enables a water-tight seal during an electronics assembly process at ambient temperatures, and then cures after UV-activation into a more rigid (i.e., higher modulus) tape that has a desirable balance of impact resistance (both tensile and shear impact), dynamic shear resistance, and pushout resistance.
