    摘要: It is an object of the present invention to provide an isocyanate group-terminated urethane prepolymer which has a low viscosity at melting and a process for producing the same, and an adhesive which comprises the urethane prepolymer and has such good workability that the adhesive in a molten state can be easily applied to substrates. The invention relates to a process for producing an isocyanate group-terminated urethane prepolymer which comprises reacting a polyol with a polyisocyanate compound, wherein the polyols comprise 10 to 60% by mass of a polyester polyol and 90 to 40% by mass of a polycarbonate polyol and a sebacic acid-derived polyester polyol which is a polycondensate of sebacic acid with a diol compound accounts for 50 to 100% by mass of the polyester polyol and wherein the polyisocyanate compound and the polyols are reacted in such amounts that the ratio (by mol) of the isocyanate group/hydroxyl group is 1.2 to 3.2. The invention further relates to an adhesive which comprises the isocyanate group-terminated urethane prepolymer as a main component.
