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: Prepn of polyesterpolyols by polycondensation of multifunctional carboxylic acids with multifunctional alcohols is effected in the following 2 stages: (1) condensation at 150-250[deg]C under normal pressure or in a vacuum of up to 10 mbar to a prod. with acid number 2-10 mg KOH/g; and (2) addn. of an esterification catalyst and condensation at 250-290 (pref 260-275)[deg]C and under a vacuum of 1-50 mbar. Also claimed is prepn of opt foamed polyurethanes from polyisocyanates, polyols of mol wt 400-10,000 and opt also low mol chain extenders, blowing agents etc, with the polyol being obtd as per stages (1) and (2) above.
