Abstract: .alpha.-(4-isocyanatophenoxy)-.psi.-(4-isocyanato-3-methyl-phenoxy)-alkanes and mixtures thereof with the corresponding methyl-free and/or dimethyl substituted diisocyanates are made by phosgenating the corresponding diamine(s).

Abstract: Polyamines containing primary amino groups are made by a one-shot process for the hydrolysis of prepolymers containing isocyanate end groups and having an isocyanate content of from 0.5 to 40 weight % with 0.75 to 40 mol of water per equivalent of isocyanate groups in the presence of very small quantities of sodium hydroxide in certain organic, polar solvents. The compounds containing isocyanate groups used for this process are isocyanate prepolymers (preferably containing urethane groups). Hydrolysis according to this process leads directly to the polyamines with elimination of carbon dioxide. These polyamines may be isolated by the usual methods and the removal of the small quantities of catalyst may advantageously be omitted. These polyamines are useful for the preparation of polyurethane(urea)s.

C. for relatively brief periods of time. Water and/or polyvalent alcohols may optionally be included in the reaction mixture. The polyisocyanates with biuret structures produced by this process are characterized by good color, good dilutability with covalent solvents and comparatively low viscosity.
