Abstract:
Adhesive compound as a permeant barrier, comprising (i) block copolymers having a construction A-B-A, (A-B)n, (A-B)nX, or (A-B-A)nX, 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.
