摘要： Polyether-based urethane-group-containing polyamines containing polymers and/or copolymers of unsaturated monomers and, optionally, urea and/or biuret and/or allophanate groups are produced by (a) reacting an NCO-prepolymer in aqueous alkaline solution at 0.degree. to 40.degree. C. to form a carbamate; (b) converting this carbamate to an amine by adding an ion exchanger to the reaction mixture; and (c) separating the polyamine from the reaction mixture. The NCO-prepolymers used as starting materials are prepolymers of (i) polyalkylene ether polyols having a molecular weight of from 1,000 to 10,000 containing from 1 to 60 wt. % of graft (co)polymers of unsaturated monomers; and (ii) excess molar quantities of organic polyisocyanate; and optionally, (iii) a low molecular weight chain-extending agent. The product polyamines have a molecular weight of from 1,000 to 10,000 and contain from 0.65 to 59.3 wt. % graft (co)polymer and from 0.11 to 2.9 wt. % terminal NH.sub.2 groups attached to the ethers by urethane groups in the polyisocyanate. The product polyamines are particularly useful in the production of polyurethanes.

摘要： A compound having a terminal isocyanate group is hydrolyzed to produce a polyamine having a urethane and/or a urea and/or a biuret group. More particularly, a carbamate is made by mixing an isocyanate prepolymer having urethane and/or urea and/or biuret groups present with aqueous base solutions at a temperature of from 0.degree. to 0.degree. C. and in quantities such that the equivalent ratio of hydroxyl to isocyanate groups is between from 0.3:1 to .gtoreq.1.01 to 1. The carbamate is then treated with an acid ion exchanger to form an amine. The amine is then removed from any other material which may be present. A preferred polyamine thus-produced corresponds to the general formula: ##STR1## in which each R radical may represent a divalent straight or branched-chain aliphatic radical; a divalent cycloaliphatic radical; a 4,4'- and/or a 2,4'-dicyclohexylmethane radical; or a 2,4- and/or 2,6-methyl cyclohexane radical. Such an amine may be reacted with a polyisocyanate and optionally with other known additives to form a polyurethane plastic or foam.

摘要： Polyamines containing aromatically bound primary amino groups having an NH.sub.2 -content of from 0.19 to 20.3 wt % are produced by a single stage process. A compound containing aromatically bound NCO-groups and having an isocyanate content of from 0.5 to 40 wt % is hydrolyzed with an excess of water in the presence of a water-miscible polar solvent and optionally a catalyst. The hydrolysis is carried out at a temperature of from -10.degree. to 150.degree. C. in a manner such that the reaction mixture is substantially homogeneous. The water-miscible polar solvent generally has a boiling point of from 56.degree. to 250.degree. C. and a dielectric constant of at least 10. This polar solvent is used in a quantity of at least 5 parts solvent for every 100 parts of isocyanate. Tertiary amines are the preferred catalysts. These polyamines are particularly useful in the production of polyurethanes.
