Abstract: The invention relates to aqueous compositions comprising a) at least one polymer PALK in the form of dispersed polymer particles, wherein the polymer PALK is obtainable by ring-opening metathesis polymerization of at least one cyclic olefin monomer, and b) at least one polymer P2 in the form of dispersed polymer particles, wherein the polymer P2 comprises no olefinically unsaturated C—C-bond and has repeating units bearing at least one polar group. The aqueous compositions are suitable in particular for producing sheetings and barrier coatings having a very good barrier action toward gases, such as air, oxygen, nitrogen, argon, carbon dioxide, and in particular toward oxygen and oxygenous gases, such as air. The sheetings and coatings also have very good mechanical properties, in particular a high elongation at break coupled with good tear strength.

Abstract: The use of an aqueous polyurethane dispersion adhesive is described for producing biodisintegratable composite foils where at least two substrates are adhesive-bonded to one another with use of the polyurethane dispersion adhesive, where at least one of the substrates is a biodisintegrable polymer foil. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from dihydroxycarboxylic acids and diaminocarboxylic acids.
