摘要： This invention relates to mixtures of polyols which are liquid at room temperature with functional aldoximes as blowing agents, wherein the aldoxime groups react with polyisocyanates to liberate carbon dioxide and are simultaneously incorporated by means of the functional group thereof into the polyurethane formed. The present invention also relates to a process for the production of polyurethane foams using these incorporated reactive blowing agents as the primary blowing agent in combination with blowing agents known in polyurethane chemistry. The process according to the invention described herein is suitable for the production of various polyurethane foams or cellular polyurethane elastomers, particularly including the production of semi-rigid and rigid polyurethane integral skin foams which are obtained by foaming the reaction mixture in closed molds.

摘要： Polyamines containing from 0.19 to 20.3 wt. % aromatically bound primary amino groups are produced by hydrolyzing an isocyanate group containing compound in the presence of excess water, a tertiary amine and, optionally an ether solvent. The hydrolysis is carried out at a temperature of from -10.degree. to 150.degree. C. in a manner such that the reaction mixture remains substantially homogeneous. The isocyanate starting material contains aromatically bound isocyanate groups and has an NCO-content of from 0.5 to 40 wt. %. The ether solvent must be water soluble and inert with respect to isocyanates. Co-solvents and catalysts may also be included in the reaction mixture. 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.
