    摘要： The invention relates to a process for the in situ production of dispersions or solutions of urea group-containing aromatic isocyanates by the low temperature reaction of aromatic diisocyanates and/or polyisocyanates (the NCO groups of which preferably exhibit different reactivities) with from 0.15 to 0.4 mols of water per NCO equivalent in relatively high molecular weight polyols and in the presence of catalysts accelerating the NCO/water reaction. Such catalysts are preferably selected from peralkylaminoalkyl ethers, peralkylamino-polyalkylene ethers and/or peralkyl-polyalkylene-polyamines. The present invention also relates to the resulting metastable solutions or dispersions and to the use thereof, optionally with the further addition of relatively high and low molecular weight compounds having hydroxyl, amino or hydrazide groups and with the optional addition of other polyisocyanates in polyurethane-forming ratios for the production of polyurethanes.

    摘要： The present invention is directed to novel urea group-containing polyisocyanates modified with long chain compounds having molecular weights of 400 to about 10,000. The present invention is also directed to a process for the preparation of modified urea group-containing polyisocyanates by reacting starting polyisocyanates which are free from urea groups with water to form urea groups in an inert reaction medium or in an aqueous mixture containing a dispersion stabilizer, wherein the starting polyisocyanates are mixed or reacted with long chain compounds having molecular weights of 400 to about 10,000 before the reacting the starting polyisocyanates with water and/or the long chain compounds are added to the inert reaction medium and/or to the water.
