    Abstract: The present disclosure relates to a pressure sensitive adhesive comprising: a) a multi-arm block copolymer of the formula Q n -Y, wherein: (i) Q represents an arm of the multi-arm block copolymer and each arm independently has the formula G-R, (ii) n represents the number of arms and is a whole number of at least 3, and (iii) Y is the residue of a multifunctional coupling agent, wherein each R is a rubbery block comprising a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or combinations thereof; and each G is a glassy block comprising a polymerized monovinyl aromatic monomer; b) a polymeric plasticizer having a weight average molecular weight M w comprised between 10.000 and 100.000 g/mol; c) at least one hydrocarbon tackifier which is primarily compatible with the rubbery blocks; d) a glassy block compatible aromatic resin having a softening point value (RBSP) of at least 150C, when measured by the ring and ball test method described in the experimental section; and e) optionally, a linear block copolymer of the formula L-(G) m , wherein L is a rubbery block comprising a polymerized olefin, a polymerized conjugated diene, a hydrogenated derivative of a polymerized conjugated diene, or any combinations thereof; and wherein m is 1 or 2. The present disclosure also relates to a method of manufacturing such a pressure sensitive adhesive and uses thereof.

    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: A curable composition comprising 20 wt.% to 60wt.%, optionally 30 wt.% to 58wt.%, or optionally 40 wt.% to 55wt.% of an acrylic block copolymer; 5 wt.% to 60wt.%, optionally 20 wt.% to 50wt.%, or optionally 15 wt.% to 45 wt.%, of an epoxy resin; 1 wt.% to 60wt.%, optionally 5 wt.% to 50wt.%, or optionally 15 wt.% to 45 wt.%, of a polyol; and 0.5 wt.% to 10wt.%, 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.
