摘要：Polyamines are produced by hydrolyzing isocyanate compounds having an NCOcontent of from 0.5 to 40 wt. % with from 0.75 to 40 moles of water per equivalent ofNCO groups in the presence of from 0.021 to 0.099 wt. % sodium hydroxide and at least10 wt. % water-miscible polar organic solvent containing nitrile, ketone, sulfoxide orether groups having a boiling point of from 56 DEG to 250 DEG C. The reaction mixture ismaintained in a homogeneous phase. The reaction is carried out at 40 DEG to 170 DEG C.These polyamines are useful in the production of polyurethane(urea)s.
