摘要： Aliphatic and/or cycloaliphatic polyisocyanates containing allophanate groups are produced by reacting (a) a di- and/or polyisocyanate with aliphatic and/or cycloaliphatic isocyanate groups with (b) a hydroxy compound at a temperature of at least 150.degree. C. for no more than 90 minutes and then rapidly cooling the reaction mixture to a temperature of less than 100.degree. C. It is preferred that the reaction be carried out in the absence of oxygen. The products thus obtained are virtually colorless, have a relatively low viscosity and excellent storage stability.

摘要： Disclosed herein is a process for recovering toluene diisocyanate (TDI) from a TDI residue solution, comprising mixing the residue solution with a polyisocyanate consisting essentially of methylenediphenyl diisocyanate (MDI) or MDI in combination with its higher ring oligomer, followed by heating the resulting mixture over a temperature range of 130.degree. to 250.degree. C. for a period of time sufficient to remove free TDI and thermally splittable TDI generated from equilibration of the TDI residue with MDI or the MDI oligomer by either a batch or continuous process.
