TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The adhesive further comprises: one or more additives, which are plasticizing agent, primary antioxidants, secondary antioxidants, processing stabilizers, light protective agent, processing aids, end-block strengthening resins or polymers, preferably elastomeric nature; and one or more fillers, preferably nanoscale fillers, transparent fillers and/or getter and/or scavenger filler. Preferred Method: The adhesive and/or the area of the electronic arrangement encapsulated by the adhesive is heated. The adhesive, after application on the electronic device, is partially or finally crosslinked. Preferred Components: The copolymer is a block, star, graft (all preferred), static and/or alternative copolymer with a weight average molecular weight of 300000, preferably 200000 g/mole, where at least one type of a first polymer block (soft block) has a softening temperature of less than -20 degrees C and at least a type of a second polymer block (hard block) has a softening temperature of greater than 40 degrees C. The soft block: is nonpolar structured and contains butylene or isobutylene as homopolymer block or copolymer block (preferred), which is copolymerized by itself or together or with further nonpolar comonomers. The hard block is from styrene, styrene derivatives, other aryl or (cyclo)aliphatic hydrocarboyl monomers, methacrylate or acrylate. The block copolymer is a triblock copolymer, which is composed of two terminal hard blocks and a midsize soft block. The adhesive resin exhibits a hydrogenation degree of at least 70%, preferably at least 95%. The adhesive resin has a diacetone alcohol cloud point value of greater than 30 degrees C, preferably 37 degrees C and mixed methylcyclohexane aniline cloud point value of greater than 50 degrees C, preferably 60 degrees C. The reactive resin has an aliphatic or cycloaliphatic nature. The photoinitiator absorbs UV light below 350 nm or UV light in a wavelength rage of 250-350 nm. The adhesive: is transparent in the visible light spectrum with a wavelength of approximately 400-800 nm; and has a Haze value of less than 5, preferably 2.5%. T EXAMPLE - No suitable example given.
