    • The present invention relates to an isocyanate-containing prepolymer obtainable by (a) contacting at least one isocyanate with at least one isocyanate-reactive compound and (b) contacting the product of step (a) with at least one amine; wherein said at least one isocyanate-reactive compound comprises at least one OH group; wherein the molar ratio of the NCO of said at least one isocyanate, to the OH of said at least one isocyanate-reactive compound is of at least 2.0; wherein said at least one isocyanate-reactive compound has a number average molecular weight of at least 2000 Da; and wherein the molar ratio of said at least one amine, to the NCO of the product of step (a) is greater than 0.4.
      The present invention also relates to a process for preparing said isocyanate-containing prepolymer. The present invention also relates to the use of said isocyanate-containing prepolymer, and to a product comprising said prepolymer.
    • 本发明涉及通过(a)使至少一种异氰酸酯与至少一种异氰酸酯反应性化合物和(b)使步骤(a)的产物与至少一种胺接触的含异氰酸酯的预聚物; 其中所述至少一种异氰酸酯反应性化合物包含至少一个OH基团; 其中所述至少一种异氰酸酯的NCO与所述至少一种异氰酸酯反应性化合物的OH的摩尔比为至少2.0; 其中所述至少一种异氰酸酯反应性化合物的数均分子量为至少2000Da; 并且其中所述至少一种胺与步骤(a)的产物的NCO的摩尔比大于0.4。 本发明还涉及制备所述含异氰酸酯的预聚物的方法。 本发明还涉及所述含异氰酸酯的预聚物和包含所述预聚物的产品的用途。
