摘要： A two component urethane structural adhesive formulation was developed containing a multi-functional aromatic amine terminated polyether as part of the curative component. The adhesive of the present invention is prepared by mixing and reacting the following low viscosity components:Component A, a curative comprising a polyol and an aromatic amine terminated polyether containing two or more primary amine groups and having a molecular weight of from 250 to about 10,000 and Component B, comprising a polyisocyanate. The adhesive of the invention is characterized by its improved sag resistance, its heavy body which is obtained without resort to included fillers or to prepolymerization of the components and by the relatively low viscosity (under about 15,000 cps) of its components which permits easy bulk handling.

摘要： Polyamines containing primary amino groups are made by hydrolyzing an isocyanate with water in the presence of a solvent which is a carboxylic acid amide. The solvent must be used in a quantity of at least 10% by weight solvent based on 100% by weight of isocyanate. The weight ratio of solvent to water must be from 3 to 200. A homogeneous phase is maintained during the hydrolysis which is carried out at temperatures of from 20.degree. to 210.degree. C. A not incorporable basic and/or metal catalyst particularly alkali metal hydroxides may be employed. The polyamines produced by this process are particularly useful for the production of polyurethanes.

摘要： The present invention relates to the use of thermosetting polyurethane urea reactive adhesive compositions which are stable at ambient temperature but rapidly set at higher temperatures, wherein the adhesive comprises stabilized finely-divided polyisocyanates of retarded reactivity of which 0.1 to 25% of the NCO-groups are surface-modified and higher and/or lower molecular polyamines (optionally with polyols as additional reactive components). An important feature of these thermosetting reactive adhesive compositions is their capacity for storage at ambient temperature and their spontaneous increase in viscosity at relatively low heating temperatures which prevents the adhesive from running off during the heating period when applied to vertical surfaces.

摘要： The invention relates to an improved process for the production of polyamines containing urethane and/or urea and/or biuret and/or isocyanurate groups and, preferably, also alkylene ether, carbonate and/or acetal groups by the alkaline hydrolysis of corresponding compounds containing terminal aliphatic and/or aromatic isocyanate groups.To this end, the compounds containing terminal NCO-groups, preferably NCO-preadducts, are converted by means of selected bases into the carbamates and neutralized by introduction into equivalent quantities of acid or by the simultaneous introduction of the components in equivalent quantities into a reaction vessel, after which the polyamines are directly isolated by methods known per se.The invention also relates to the use of the polyamines obtained by the process for 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 primary amino groups are prepared in a single stage process by hydrolyzing an isocyanate in the presence of a catalyst incorporable through an NCO reactive 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 has an NCO content of from 0.5 to 40% by weight. The catalyst is used in a quantity of at least 0.0001% by weight, based on 100% by weight of isocyanate compound. The water-miscible solvent is used in a quantity of at least 10% by weight, based on 100% by weight of isocyanate compound. The polyamines thus produced are particularly useful in the production of polyurethanes.
