    摘要： The invention relates to hydroxyl-functionalised polyurethane hot melt prepolymers comprising the chemical reaction product of isocyanate-reactive starting materials with at least one isocyanate-containing starting material. Said prepolymers are characterized in that the isocyanate-reactive starting materials of the hydroxyl-functionalised polyurethane hot melt prepolymers have a polypropylene glycol with a functionality higher than two and a number-average molar mass higher than or equal to 3,000 g/mol, a polypropylene glycol with a functionality less than or equal to two and a number-average molar mass less than or equal to 1,000 g/mol, and a chain lengthener with a functionality less than or equal to 500 g/mol, and the isocyanate-containing starting material of the hydroxyl-functionalised polyurethane hot melt prepolymer has an aliphatic or alicyclic diisocyanate.
