Beschreibung
Zusammenfassung:	Crosslinked pressure-sensitive adhesive comprising at least one base polymer component obtainable by free-radical copolymerization of the following monomers: a) linear acrylic esters having 2 to 10 C atoms in the alkyl radical, b) branched, non-cyclic acrylic esters having a glass transition temperature T g (based on the DSC measurement to DIN 53765) of not more than - 20°C, c) 8% to 15% by weight of acrylic acid, d) optionally up to 10% by weight of further copolymerizable monomers, characterized in that the ratio of the linear acrylic esters to the branched acrylic esters is in the range from 1 : 6 to 10 : 1 mass fractions. Un adhésif réticulé sensible à la pression comprenant au moins un composant polymère de base pouvant être obtenu par une copolymérisation à radicaux libres pour les monomères suivants : a) esters acryliques linéaires ayant 2 à 10 atomes C dans le radical alkyle, b) des esters ramifiés acryliques non cycliques ayant une température de transition de verre Tg (basée sur la mesure DSC à la norme DIN 53765) dau plus -20 °C, c) 8 % à 15 % en poids dacide acrylique, d) éventuellement jusquà 10 % en poids dautres monomères copolymérisables, caractérisés en ce que le rapport des esters acryliques linéaires aux esters acryliques ramifiés se situe dans la plage de 1:6 à 10:1 de fractions massiques.
