    摘要： Aqueous dispersions of crosslinked polyurethane ionomers can be advantageously obtained by a method in which polyurethane prepolymers possessing salt groups and aliphatically and/or cycloaliphatically bonded terminal isocyanate groups, in a water-miscible organic solvent, are mixed with polyfunctional polyisocyanates, the resulting solution is dispersed in water and the organic solvent is evaporated off.

    摘要： The invention concerns a process for making heat-resistant polyurethane elastomers from substantially linear polyhydroxyl compounds of high molecular weight, polyisocyanates, chain extenders, and, if desired, catalysts and additives, in which the polyhydroxyl compound is reacted with diisocyanate material in amounts to give an OH:NCO ratio of 1:1.10 to 1:2 and produce an adduct, and the adduct is subsequently reacted with symmetrical aromatic diisocyanate and a diol as chain extender (preferably a linear diol containing 2,4 or 6 carbon atoms) to obtain a crystalline or crystallizable diurethane or polyurethane of good heat resistance.
