Abstract
The present invention relates to compositions comprising reaction products of a polyisocyanate with a polyester block copolymer and a process for the preparation thereof. These are suitable as a moisture-curing hot melt adhesive. The hot melt adhesive composition may optionally also comprise a reaction product of a polyisocyanate with a polyester polyol and/or a reaction product of a polyisocyanate with a polyether polyol. Such polyurethane hot melt adhesive compositions have good creep resistance and interfacial adhesion values on plastics and show very high strength values.
