ABSTRACT:
One-component moisture-curing hot melt adhesive compositions based on reaction products from di- or polyisocyanates and polyether-polyols, crystalline or partly crystalline polyester-polyols and low molecular weight polymers from olefinically unsaturated monomers and optionally hydroxylated tackifying resins are suitable for high-strength and ageing-resistant gluing of profiles of plastics to one- or multilayer acrylate films.
