    Abstract: Production of functionalized polyurethane foams comprises: (a) reacting an isocyanate with a compound having at least two isocyanate-reactive hydrogen atoms and a compound (I) having at least one hydroxy, amino and/or thiol group and at least one group R selected from halogen, carbonyl, ester, anhydride, epoxy, carboxy and sulfone groups; and (b) applying an R-reactive compound (II) to the resulting polyurethane foam so that (II) is covalently bound to (I) through R. An independent claim is also included for polyurethane foams produced by the above method.

    Abstract: Polyisocyanates are prepared by production of an addition product containing an isocyanate reactive group and an isocyanate group by reaction of a diisocyanate with compounds having two isocyanate reactive groups whereby at least one of components have functional groups having different reactivity to opposite functional groups of the other components. Polyisocyanates (I) are prepared by (A) production of an addition product containing an isocyanate reactive group and an isocyanate group by reaction of (A1) a diisocyanate with (A2) compounds having two isocyanate reactive groups whereby at least one of components (A1) or (A2) have functional groups having different reactivity to opposite functional groups of the other components. (B) optionally intermolecular addition reaction of the addition product (A) to form a polyaddition product that contains an isocyanate reactive group and an isocyanate group. (C) reaction of the addition product (A) and /or the polyaddition product from (B) with a di- or polyisocyanate (C1) that is different to (A1). An Independent claim is included for the polyaddition product (B).

    Abstract: In a process for the production of dendrimeric or highly-branched polyurethanes (PU) by reacting di- and/or poly-isocyanates with NCO-reactive compounds, at least one of the reactants has functional groups with different reactivity towards the other reactant and the reaction conditions are chosen so that only certain groups react together at each stage. Independent claims are also included for dendrimeric PU and highly-branched PU obtained by this process.

    Abstract: The invention relates to a method for producing double metal cyanide compounds, comprising the following stages: a) reacting a solution of a metal salt of general formula M m(X)n with a solution of a cyanometallate compound of formula HaM (CN)b(A)c, M and M being metal cations, X and A each representing an anion and a, b, c, m and n being whole numbers selected to guarantee the electroneutrality of the particular salt and at least one of the two solutions containing at least one water-soluble organic ligand containing heteroatoms; b) combining the resulting suspension with a water-miscible ligand which can be the same as or different from the ligand used in a); and c) separating the double metal cyanide compound from the suspension. At least one of the educt solutions used in a) contains at least one inert inorganic or organic solid which is insoluble in the educts and end products.
