摘要： A pressure-sensitive adhesive which develops a high bond strength to substrates of low surface energies, even at low temperatures. The adhesive is composed of a first block copolymer A-B and a second block copolymer which is composed of at least two and not more than eleven connected subunits A-B, A being in each case a polymer block comprising vinylaromatic monomer units and B being in each case a poly(1,3-diene). The first block copolymer is present in the adhesive in a fraction of at least 50% by weight, based on the total mass of the block copolymers in the adhesive. The adhesive additionally contains tackifier resins, of which at least 30% by weight are liquid at room temperature and which are miscible with the polymer blocks B, but not with the polymer blocks A. An adhesive tape with the pressure-sensitive adhesive is also described.

摘要： Pressure-sensitive adhesive for single- or double-sidedly tacky pressure-sensitive adhesive strips redetachable without residue or destruction both by extensive stretching substantially in the bond plane and by peeling, the pressure-sensitive adhesive being composed at least of (1) a vinylaromatic block copolymer, (2) a solid tackifying resin having a softening temperature by the ring-and-ball method of more than 30° C. and (3) a resin which is liquid at room temperature (23° C.), the fraction of liquid resin accounting for at least 40% by weight, based on the total amount of resin. Strips formed from the adhesive and the use of the strips to form redetachable bonds are also disclosed.
