| description | Highly functionalized polyisocyanates are prepared by reaction of a di- or polyisocyanate with compounds having at least three and/or two isocyanate reactive groups whereby at least one of components have functional groups having different reactivity and whereby the reaction ratio is chosen such that on average the addition product contains one isocyanate reactive group; Highly functionalized polyisocyanates (I) are prepared by (A) production of an addition product containing an isocyanate reactive group and at least two isocyanate groups by reaction of (A1) a di- or polyisocyanate with (A2) compounds having at least three isocyanate reactive groups and /or (A3) compounds having two isocyanate reactive groups whereby at least one of components (A1)-(A3) have functional groups having different reactivity to the opposite functional groups of the other components and whereby the reaction ratio is chosen such that on average the addition product (A) contains one isocyanate reactive group. (B) optionally intermolecular addition reaction of the addition product (A) to form a polyaddition product that, on average, contains one isocyanate reactive group and more than two isocyanate groups (C) reaction of the addition product (A) and/or the polyaddition product (B) with a di- or polyisocyanate (C1). An Independent claim is included for the polyaddition product (B) |
