    摘要： This invention relates to a process for the production of polyurethane urea products from isocyanate product blends and preferably less reactive, aromatic diamines, or solutions of aromatic diamines in relatively high molecular weight polyhydroxyl compounds, the reaction components being reacted in a casting process with commercially-reasonable casting times and comparatively short demolding times. For this purpose, relatively high-molecular weight polyhydroxyl compounds, optionally in the presence of low molecular weight diols are reacted with excess quantities of toluene, phenylene or hexamethylene diisocyanate to produce a substantially diisocyanate-free NCO-prepolymer. This NCO-prepolymer is mixed with from 0.1 to 25%, by weight, of less reactive, monomeric tetra-alkyl-diphenylmethane diisocyanates corresponding to the general formula: ##STR1## wherein R.sub.1 to R.sub.4, which may be the same or different, represent C.sub.1 -C.sub.4 alkyl radicals.These isocyanate blends may be easily processed into elastomer moldings having favorable properties in the casting process using moderately-reactive aromatic diamines from the series of di- to tetra-alkyl-diphenylmethane diamines and/or dialkyl-toluene diamines and/or using substituted 3,5-diamino-4-alkyl-benzoic acid alkyl esters, optionally dissolved in the relatively high molecular weight polyhydroxyl compounds.

    摘要： Preparations of surface-deactivated solid isocyanates which are dispersed in finely particulate manner, with aqueous isocyanate-reactive polymer dispersions that include a) dispersed polymers having isocyanate-reactive groups, b) dispersed surface-deactivated oligomeric solid polyisocyanates, and c) at least one catalyst, where the catalyst or the totality of catalysts accelerates the reaction of the monomeric polyisocyanates which form by the thermal cleavage of the oligomeric polyisocyanates more strongly than the thermal cleavage itself. The preparations are prepared by mixing aqueous dispersions of at least one isocyanate-reactive polymer with at least one dispersed surface-deactivated oligomreric solid polyisocyanate and at least one catalyst. The preparations can be used in binders, films and powders for bonded joints, or coatings and to make a latently cross-linking adhesive layer. Substrates can be coated with layers obtainable with the above-described preparations.
