摘要： A urethane prepolymer composition useful as sealant is disclosed. The composition comprises a reaction product of an organic polyisocyanate and a polyether polyol mixture at an NCO/OH equivalent ratio from 1.6 to 2.5. The polyether polyol mixture contains (a) from 75 to 95 % by weight of the mixture of a polyoxyalkylenediol having an average MW from 400 to 1,000 and an oxyethlene unit content greater than 50 % by weight, and (b) the balance of the mixture of a polyoxyalkylenetriol having an average MW from 5,000 to 10,000 and an oxyethylene unit content greater than 50 % by weight. An equivalent composition is produced by reacting the polyoxyalkylenediol and polyoxyalkylenetriol with the organic polyisocyanate separately and mixing together after the reaction.
