Claim Text:
1. An isocyanate-terminated prepolymer C having an NCO content of from ≧26.0% by mass to ≦31.0% by mass, based on the mass of the prepolymer C, obtained from the reaction of (i) an isocyanate composition A having a viscosity at 25° C. of from ≧60 mPas to ≦800 mPas, comprising (ii) a polyester ether polyol B having an average functionality of from ≧1.9 to ≦2.1 and an OH number of from ≧200 mg(KOH)/g to ≦500 mg(KOH)/g, obtained from the reaction of a dicarboxylic acid and/or a dicarboxylic acid derivative B1 with at least one polyol B2 and with an epoxide B3,
