    摘要: The present invention relates to a reactive hot melt adhesive composition, a polyurethane prepolymer composition, and cured product thereof having a high mechanical strength and an excellent bonding strength as well as a better reworkability. In particular, the present invention relates to a reactive hot melt adhesive composition comprising: 10% to 24% by weight of a polyisocyanate, 40% to 73% by weight of a first polyol having a number average molecular weight larger than 1,500 g/mol, 1% to 25% by weight of a (meth) acrylate polymer having a number average molecular weight of 20,000 to 80,000 g/mol, and 1% to 15% by weight of a diluent, in which the weight percentages are based on the total weight of all components of the composition.
