    摘要: Polyamines containing aromatically bound primary amino groups are prepared in a single stage process by hydrolyzing an isocyanate in the presence of a compound containing an amidine and/or guanidine group and a water-miscible, aprotic-dipolar solvent. This hydrolysis is carried out at from 20.degree. to 210.degree. C. with the reactants being in substantially homogeneous phase. The isocyanate starting material contains aromatically bound NCO groups and has NCO content of from 0.5 to 40 wt. %. The compound containing amidine and/or guanidine groups functions as a catalyst and is used in a quantity of at least 0.001 parts by weight for every 100 parts by weight of isocyanate. The water-miscible solvent is used in a quantity of at least 10 parts by weight for every 100 parts by weight of polyisocyanate. The polyamines thus-produced are particularly useful in the production of polyurethanes.

    摘要: Modified polyamines containing carbamates, urethane and/or urea and/or thiourethane groups and having a primary amine content of from 0.1 to 20.2 wt % are produced by (a) mixing an organic isocyanate with a base in the presence of at least one hydrogen-active compound and water and (b) converting the carbamate, urethane and/or urea and/or thiourethane groups to amino groups. The isocyanate starting material has an isocyanate content of from 0.5 to 40 wt. %. The hydrogen-active compound contains a hydroxy and/or amino and/or thiol group. Water is used in a quantity such that one mol of water is present for each isocyanate equivalent. Conversion to form the amino groups is accomplished by treatment with a proton donor and/or thermal decomposition and/or solvent extraction. The polyamines thus-produced are particularly useful in the production of polyurethanes.
