    Abstract: The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include an alkyl(meth)acrylate ester having 1 to 24 carbon atoms in the alkyl group and a free-radical generating initiator. Within a temperature range of between −30° C. to 90° C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed 2 MPa, a shear creep compliance (J) of at least 6×10″6 1/Pa measured at 5 seconds with an applied shear stress between 50 kPa and 500 kPa, and a strain recovery of at least 50% at at least one point of applied shear stress within the range of 5 kPa to 500 kPa within 1 minute after removing the applied shear stress. In a preferred embodiment, the flexible device is a flexible electronic display.

    Abstract: The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film, having a first pressure sensitive adhesive layer and at least an opposing layer, wherein the first pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition with a (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising: (a) a first monomer which is an alkyl (meth)acrylate ester of a primary alcohol R1—OH, the alkyl (meth)acrylate ester being of Formula (I) CH2═C(R2)—(CO)—OR1   (I) wherein R1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R1—OH has an iso index equal to at least 2 but no greater than 4; R2 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group; wherein the at least one opposing layer comprises at least one filler material. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.

    Abstract: Adhesives compositions and methods of preparing adhesive compositions are described. The methods generally comprise a) providing a syrup composition comprising i) a free-radically polymerizable solvent monomer; and ii) a solute (meth)acrylic copolymer; and b) radiation curing the syrup composition in the absence of an ionic photoacid generator. In one embodiment, the solute (meth)acrylic copolymer as provided or during curing comprises repeat units derived from at least one alkyl(meth)acrylate monomer, at least one ethylenically unsaturated monomer comprising an acid-functional group; and at least one (meth)acryloyl monomer comprising an epoxy-functional group; and the acid-functional groups crosslink with the epoxy-functional groups. In another embodiment, the solute (meth)acrylic copolymer comprising repeat units derived from at least one alkyl(meth)acrylate monomer and at least one ethylenically unsaturated monomer comprising an acid-functional group; and an epoxy resin, having on average greater than one polymerizable epoxy group per molecule, crosslinks the acid-functional groups.
