Abstract (en)
[origin: WO2007131674A1] Branched polyols (A) having a statistical average of two or more hydroxyl groups in the molecule, prepared by the reaction of (A1) at least one polyisocyanate containing a statistical average in the molecule of two or more isocyanate groups and - two or more hard segments (a11) which, as constituents of a thermoset three-dimensional network, increase its glass transition temperature, or two or more soft segments which, as constituents of a thermoset three-dimensional network, lower its glass transition temperature, with (A2) at least one polyol of the general formula I: X [-R(-OH)<SUB>n</SUB>]<SUB>m</SUB> (I) in which the index and the variables are each defined as follows: n is from 1 to 5, m is 1 or 2, X is an isocyanate-reactive functional group and R is a divalent to pentavalent organic radical, with the proviso that R contains at least one hard segment (a11) or consists thereof when (A1) contains soft segments, in a molar (A2): (A1) ratio of = 2 and an equivalents ratio of [X + OH] : NCO = 2; process for their preparation and use thereof.
