    摘要： The present invention relates to reactive polyurethanes having a low monomeric diisocyanate content and also to their preparation and their use in reactive one- and two-component adhesives/sealants, assembly foams, casting compounds, and also flexible, rigid and integral foams. The polyurethanes are prepared in the presence of zirconium(IV) acetylacetonate complexes as catalyst, where at least one acetylacetonate ligand present in the catalyst bears a fluorine substituent.

    摘要： Method for the production of adhesive-coated articles, articles obtainable thereby and their use A method for the production of adhesive-coated articles comprises the steps of: (I) providing a substrate; (II) applying a first polyurethane and/or polyurethane-polyurea polymer onto the substrate, the first polyurethane and/or polyurethane-polyurea polymer being capable of attaining an at least partially crystalline state with a final degree of crystallinity and wherein during and/or after the application the first polyurethane and/or polyurethane-polyurea polymer is present in a non-crystalline state. The method further comprises the steps: (III) applying onto the first polyurethane and/or polyurethane-polyurea polymer of step (II) a composition comprising a mixture of a second polyurethane and/or polyurethane-polyurea polymer and furthermore an acrylate polymer, wherein the application is performed while the degree of crystallinity of the first polyurethane-polyurea polymer is lower than its final degree of crystallinity; and (IV) cooling the article obtained to a temperature below the glass transition temperature of the acrylate polymer.
