Abstract: The present invention relates to curable barrier encapsulants or sealants for electronic devices that have pressure sensitive adhesive properties. The encapsulants are especially suitable for organic electronic devices that require lower laminating temperature profiles. The encapsulant protects active organic/polymeric components within an organic electronic device from environmental elements, such as moisture and oxygen.

Abstract: Hot melt adhesives with pressure sensitive adhesive properties for electronic devices are described. The hot melt adhesive comprises a styrenic block copolymer with fully hydrogenated and saturated soft blocks, a liquid diluent or a tackifier, a (meth)acrylate monomer or an oligomer having at least two (meth)acrylic functionalities per oligomer chain, and an initiator. The hot melt adhesive is also a reworkable UV curable optically clear adhesive film. The adhesive and film are suitable as a laminating PSA film or encapsulant for LCD display, LED display, touch screen, and flexible thin film photovoltaic module.

Abstract: An ultraviolet (UV) crosslinkable acrylic pressure sensitive adhesive comprises an acrylic copolymer and a cationic photoinitiator. The acrylic copolymer comprises pendant reactive functional groups. The pressure sensitive adhesive formed from the acrylic copolymer with the pendant reactive functional groups result in high green strength and/or high temperature holding strength of the adhesive.

Abstract: A novel silicone-acrylic copolymer which comprises a covalently bonded silicone polymer with an acrylic polymer through the —Si—O—Si— linkage is described. The silicone-acrylic copolymer is a reaction product of (a) a silicone polymer, (bi) a mixture of acrylic monomers wherein at least one acrylic monomer comprises a silane (meth)acrylic monomer and/or a siloxane (meth)acrylic macromer with a radical initiator to form an acrylic prepolymer or (bii) an acrylic polymer which comprises a silane or a siloxane functional group; and (c) a scrambling catalyst, wherein the ratio of the silicone polymer (a) and the mixture of acrylic monomers (bi) or polymer (bii) is from 50:1 to 1:50. The silicone-acrylic copolymer is useful as an adhesive, sealant, coating, and the like.

Abstract: UV-crosslinkable acrylic hotmelt pressure sensitive adhesives comprising acrylic and vinyl monomers, and a polymerizable UV photoinitiator. The photoinitiator comprises a spacer comprising both ethylene oxide and urethane, or urea, carbonate, or siloxane functional groups. The ethylene oxide is directly bonded to the chromophore (e.g., benzophenone) moiety, while the urethane (or urea, carbonate, siloxane) is closely linked to the polymerizable moiety (e.g., styrenic C?C double bond).
