    Abstract: Pressure sensitive adhesives are provided comprising an adhesive copolymer which is a copolymer of a set of monomers comprising: a) 41.0-49.0 weight percent of isobornyl acrylate (IBOA); b) 0.0-4.5 weight percent of one or more basic-functional polar monomers comprising a polymerizable double bond; and c) 46.5-58.9 weight percent of one or more alkyl (meth)acrylate monomers, where the alkyl groups are selected from linear and branched alkyl groups comprising 2-12 carbon atoms and branched alkyl groups comprising 13-20 carbon atoms and wherein weight percentages are weight percent of all monofunctional monomers comprising the adhesive copolymer. In another aspect, the present disclosure provides tapes comprising the pressure sensitive adhesive according to the present disclosure. In some embodiments, the tapes are flexographic plate mounting tapes.

    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 6xl0" 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.
