formulation for making sticky tapes and labels. SUBSTANCE: composition is prepared by copolymerization of monoalkenyl arene and diene with conjugated double bonds and having 4 or 5 carbon atoms. Composition comprises wt %: (a) unbounded linear block copolymers, 30-55; (b) bonded linear block copolymers, 25-40; (c) branched block copolymers, 20-40. Adhesive composition comprises main polymer, one or more adhesiveness-increasing resins, and optionally, one or more antioxidants and thinning resin and/or thinning oil. Main polymer is composition of block copolymers. Composition is highly heat resistant and has high adherence. EFFECT: improved properties of the adhesive composition. 19 cl, 7 ex, 3 tbl
