Adhesive compound as a permeant barrier, comprising (i) block copolymers having a construction A-B-A, (A-B), (A-B)X, or (A-B-A)X, where X is the radical of the coupling reagent, n is a whole number between 2 and 10, A is a polymer made of a vinyl aromatic compound and B is a polymer block made of an alkene or diene, wherein this polymer block can also be hydrated, with the condition that at least part of the A blocks is sulfonated, optionally with two-block copolymers in the form of A-B as an admixture component, and (ii) at least one tackifier resin.

Cross-linkable adhesive compound with hard and soft blocks as a permeant barrier

Temperature-stable adhesive compound, comprising (i) block copolymers having a construction A-B-A, (A-B), (A-B)X, or (A-B-A)X, where X is the radical of a coupling reagent, n is an integer between 2 and 10, A is a polymer block of a vinylaromatic, and B is a polymer block of an alkene or diene, at least some of the A blocks being sulfonated, and optionally diblock copolymers of the form A-B, and
