    • High-functionality polyisocyanates are prepared by a process which comprises (i) preparation of an addition product (A) which contains one group which is reactive toward isocyanate and at least two isocyanate groups by reacting (a) a diisocyanate or polyisocyanate I with (b1) compounds having at least three groups which are reactive toward isocyanate or (b2) compounds containing two groups which are reactive toward isocyanate or mixtures of (b1) and (b2), where at least one of the components (a) or (b) has functional groups having differing reactivities toward the functional groups of the other component and the reaction ratio is selected so that the addition product (A) contains an average of one group which is reactive toward isocyanate, (ii) if desired, intermolecular addition reaction of the addition product (A) to form a polyaddition product (P) containing an average of one group which is reactive toward isocyanate and an average of more than two isocyanate groups, and (iii) reaction of the addition product (A) and/or the polyaddition product (P) with a diisocyanate or polyisocyanate II.
    • 通过以下方法制备高官能度多异氰酸酯:(i)通过使(a)二异氰酸酯或多异氰酸酯I与(b1)反应,制备含有一个对异氰酸酯和至少两个异氰酸酯基反应的基团的加成产物(A) )具有至少三个对异氰酸酯反应的基团的化合物或(b2)含有对异氰酸酯或(b1)和(b2)的混合物具有反应性的两个基团的化合物,其中至少一种组分(a)或(b) 具有与其他成分的官能团反应性不同的官能团,选择反应比,使加成产物(A)含有对异氰酸酯具有反应性的一个基团的平均值,(ii)如果需要,分子内加成反应 加成产物(A)形成含有平均一个对异氰酸酯反应的基团和平均多于两个异氰酸酯基团的加聚产物(P),和(iii)反应 加成产物(A)和/或加聚产物(P)与二异氰酸酯或多异氰酸酯II的离子。
