A block copolymer composition is disclosed which derives from the copolymerization of a monoalkenyl-arene and a conjugated diene having from 4 to 5 carbon atoms, and comprising: from 30% to 55% by weight, preferably from 34% to 50%, of non-coupled linear structures; from 25% to 40% by weight, preferably from 30% to 35% by weight, of coupled linear structures; from 20% to 40% by weight, preferably from 24% to 35% by weight, of branched structures. The preparation of said composition and its use in the formulation of adhesive tapes and labels are disclosed as well.
