Abstract: Aqueous dispersions comprising a polyurethane synthesized from a) diisocyanates, b) diols of which b1) from 10 to 100 mol %, based on the total amount of diols (b), have a molecular weight of from 500 to 5 000, and b2) 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 appropriate, 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 appropriate, monofunctional compounds other than the monomers (a) to (d), containing a reactive group which is an alcoholic hydroxyl group, a primary or secondary amino group or an isocyanate gro

Abstract: Process for preparing (meth)acrylic esters, in which chromanol derivatives are used as stabilizers against polymerization, and the use of the thus obtainable (meth)acrylic esters.

Abstract: Aqueous dispersions comprising a polyurethane composed of (a) diisocyanates, (b) diols, (c) monomers, excluding monomers (a) and (b), containing at least one isocyanate or isocyanate-reactive group and further carrying at least one hydrophilic group to render the polyurethane dispersible in water, d) optionally, polyfunctional compounds, excluding monomers (a) to (c), containing alcoholic hydroxyl, primary or secondary amino, or isocyanate reactive groups, and (e) optionally, monofunctional compounds, excluding monomers (a) to (d), containing an alcoholic hydroxyl, primary or secondary amino, or isocyanate reactive group, obtained by reacting the monomers (a), (b), (c), and, optionally (d) and (e), in the presence of a cesium salt.
