Abstract: The invention relates to aqueous dispersions comprising a polyurethane, produced from a) diisocyanates, b) diols, of which b1) 10 to 100 mol. %, relative to the total amount of diols (b), have a molecular weight of 500 to 5000 and b2) 0 to 90 mol. %, relative to the total amount of diols (b), have a molecular weight of 60 to 500 g/mol, c) various monomers from amongst the monomers (a) and (b) with at least one isocyanate group or at least one group reactive towards isocyanate groups, with furthermore, at least one hydrophilic or potentially hydrophilic group, by means of which the aqueous dispersibility of the polyurethane is affected, d) optionally additional polyfunctional compounds different from the monomers (a) to (c), said functions being alcoholic hydroxy groups, primary or secondary amino groups or isocyanate groups and e) optionally additional monofunctional compounds different from the monomers (a) to (d), said function being an alcoholic hydroxy group, a primary or secondary amino group or an isocyanate group. Said dispersions may be obtained by reaction of the monomers a), b), c) and optionally d) and e) in the presence of a caesium salt.

Abstract: Aqueous dispersions comprising a polyurethane composed of a) diisocyanates, b) diols of which b 1 ) from 10 to 100 mol %, based on the total amount of diols (b), have a molecular weight of from 500 to 5000, and b 2 ) from 0 to 90 mol %, based on the total amount of diols (b), have a molecular weight of from 60 to 500 g/mol, c) monomers other than the monomers (a) and (b), containing at least one isocyanate group or at least one isocyanate-reactive group and further carrying at least one hydrophilic group or potentially hydrophilic group by means of which the polyurethane is made dispersible in water, d) if desired, further, polyfunctional compounds other than the monomers (a) to (c), containing reactive groups which are alcoholic hydroxyl groups, primary or secondary amino groups or isocyanate groups, and e) if desired, monofunctional compounds which are other than the monomers (a) to (d) and contain a reactive group which is an alcoholic hydroxyl group, a primary or secondary amino group or an isocyanate group, obtainable by reacting the monomers a), b), c), and, where used, d) and e) in the presence of a cesium salt.
