    • Polymer-containing polyether polyamines containing terminal aromatically-bound amino groups are produced by in situ polymerization of a polyether polyamine with an olefinically unsaturated monomer. The polyether polyamine starting material must have terminal aromatic amino groups, a molecular weight of from 800 to 10,000 and an aromatic amino group content of from 0.3 to 16 wt. %. Suitable olefinically unsaturated monomers include .alpha.,.beta.-unsaturated nitriles, aromatic vinyl compounds, .alpha.,.beta.-unsaturated carboxylic acids and esters thereof, vinyl esters, vinyl halides, vinylidene halides, .alpha.,.beta.-unsaturated carboxylic acid amides and aminoalkyl esters of unsaturated carboxylic acids. Acrylonitrile/styrene mixtures are preferred monomers. The starting materials are employed in quantities such that the product modified polyether polyamine contains from 1 to 60 wt. % polymer or graft-polymer. The product polyamines are particularly useful in the production of polyurethanes.

    • This invention relates to an improved process for the preparation of aromatic polyamines containing urethane and/or biuret and/or urea and/or isocyanurate groups and preferably also ether groups by the hydrolysis of poly-N-monoaryl-N',N'-dialkyl urea compounds (1-aryl-3,3-dialkyl ureas). The ureas are obtained by the reaction of secondary aliphatic, cycloaliphatic or saturated heterocyclic amines with divalent to tetravalent isocyanate compounds containing isocyanate end groups attached to aromatic residues. The ureas correspond to the general formula: ##STR1## wherein R.sup.1, R.sup.2 denote alkyl or cycloalkyl groups, or together form a ring andA denotes a divalent to tetravalent residue attached to the ureas by aromatic groups.Hydrolysis is carried out in the presence of water and up to two equivalents of a base containing hydroxide ions and/or up to two equivalents of a compound containing tertiary amino groups, optionally in the presence of solvents. The use of the polyamines obtained by this process for the synthesis of polyurethanes is also described.
