    摘要： The present invention relates to a process for the production of polyisocyanate compositions containing urethane groups and having an isocyanate content of about 0.5 to 45% by weight by the reaction of(a) an organic polyisocyanate or mixtures thereof having an isocyanate content of about 30 to 50% by weight with(b) organic polyhydroxyl compounds using an equivalent ratio of isocyanate groups to hydroxyl groups of at least 1.8:1, characterized in that the polyhydroxyl compounds (b) are based on(b1) polyhydroxypolyacrylates having an average molecular weight, determined by vapor pressure osmometry, of 232 to about 100,000 which optionally contain urethane or ester groups in side chains, and a statistical average of at least one alcoholic hydroxyl group per molecule(b2) optionally in admixture with up to about 250% by weight, based on (b1), of other polyhydroxyl compounds in the molecular weight range of 62 to about 12,000.The invention also relates to the polyisocyanate compositions obtainable by this process and their use as components for the production of polyurethanes or polyurethane ureas.

    摘要： Homogeneous storable mixtures containing small quantities of salts and having a high mixed hydroxyl number of mixed hydroxyl/amine number are made by mixing (a) a polyoxyalkylene polyol and/or polyolamine and/or polyamine based on an alkyloxirane having a molecular weight of from 400 to 12,000, (b) a low molecular weight polyol which is not completely miscible with (a) and a solution-promoting additive in quantities such that for every 100 parts of (a), from 1 to 200 parts of (b) and from 0.01 to 10 parts of (c) are present. The solution-promoting additives are salts of cations of Groups IA, IIA and IIIA of the Periodic System of Elements or ammonium or mono- to tetra-alkylammonium ions and anions formed by removing at least one proton from an acid having a K.sub.s -value of at least 10.sup.-7. These mixtures are particularly useful in the production of polyurethanes.
