Beschreibung
Zusammenfassung:	The invention relates to a method for reducing rest tackiness of moisture curing polyurethane hot-melt adhesives and to use of crystalline monofunctional alcohols in moisture curing polyurethane hot-melt adhesives for reducing the rest tackiness of the adhesive composition. The method for reducing rest tackiness comprises adding at least one crystalline monofunctional alcohol to a mixture from which the moisture curing polyurethane hot-melt adhesive composition is prepared. The at least one crystalline monofunctional alcohol can be added to a mixture containing one or more polyols, and one or more monomeric polyisocyanates and/or one or more isocyanate-functional polyurethane prepolymers.
