    摘要： A continuous process for the preparation of an isocyanate-terminated prepolymer having an NCO content in the range from 2 to 15% by weight, said process comprising the steps of :

    (A) continuously delivering to a reaction zone an organic polyisocyanate composition and an isocyanate reactive compound having an average molecular weight of at least 1000 the relative proportions of isocyanate composition and isocyanate reactive compound being appropriate for the formation of a prepolymer having an NCO content in the indicated range;
    (B) allowing the isocyanate composition and the isocyanate reactive compound to react in the reaction zone to form an isocyanate-terminated prepolymer, and
    (C) continuously removing the prepolymer from the reaction zone.
