    摘要: A process for the preparation of polyisocyanates which contain one or more biuret groups, by reacting a) an aliphatic or cycloaliphatic isocyanate containing two or more isocyanate groups (isocyanate a) with b) a tertiary alcohol or a mixture of water and a tertiary alcohol (biuretizing agent b) at from 100 to 250° C., which comprises carrying out the reaction in the presence c) of a stabilizer (c) which constitutes a catalytic amount of urea, ammonia, biuret, a urea derivative of the formula I in which R1, R2, R3 and R4 are hydrogen, C1 to C10 alkyl or C5 to C10 aryl, or a carboxamide of the formula II in which R5 is C1 to C12 alkyl which is unsubstituted or in which 1, 2 or 3 hydrogen atoms are replaced by a radical

    摘要: The present invention relates to a process for preparing high-functionality polyetherols by reacting at least one trifunctional or higher-functionality alcohol and if appropriate further di- and/or monofunctional alcohols and/or modifying reagents, with the aid of acidic catalysts, where the trifunctional or higher-functionality alcohol is not glycerol. The present invention further relates to high-functionality polyetherols obtainable by such a process and to the use of these high-functionality polyetherols as adhesion promoters, thixotropic agents, rheology modifiers of polymers, phase transfer reagents, micro- or nanocontainers for biologically active compounds, for example for active medical ingredients, biocides, herbicides or fungicides, as pigment dispersants, an additive in printing inks or as structural units for preparing polyaddition or polycondensation polymers or for treatment of seed.

    摘要: Branched polyesters with sulfonate groups can be obtained by reacting components A, B, optionally C, and optionally D to yield branched polyesters, then reacting these branched polyesters with hydrogen sulfite. Component A is at least one α,β-olefinically unsaturated dicarboxylic acid, component B is at least one di- or higher-functional alcohol, optional component C is at least one di- or higher-functional carboxylic acid or hydroxycarboxylic acid without an α,β-olefinically unsaturated bond, and optional component D is at least one compound of formula CH3(—O—CH2—CH2)n—OH. In reacting the branched polyesters with hydrogen sulfite, a molar amount of hydrogen sulfite is at most 95 mol %, based on an amount of α,β-olefinically unsaturated dicarboxylic acid.
