IPC: C08G12/30
Filed: 1948-03-08
Abstract: Thermosetting and air-drying resins of use in paints, lacquers and varnishes are made by condensing an aminotriazine of formula <FORM:0653827/IV (a)/1> where R is the hydrocarbon residue of a drying oil amine, e.g. from soya bean, tung, linseed, cotton seed, cod liver or croton oils, and A and B may be amino, alkylated amino, e.g. ethyl-, butyl-, octyl-, or tetradecyl-amino, or the group -NHR. The condensation may be carried out in an alcohol, and 1-6 mols, of aldehyde per mol. of triazine are used.  Specified aldehydes are formaldehyde, acetaldehyde, butylaldehyde, furfural and compounds such as hexamethylenetetramine.  In two examples, aqueous formaldehyde is heated with 2-alkyl-amino-4 : 6-diamino-1 : 3 : 5-triazine (where the alkyl group is that derived from soya amines, i.e. C18), with azeotropic removal of water, and the resin is air-dried or baked at 300 DEG  F.; butanol, which serves as an alkylating agent may be present during the polymerization.ALSO:N-substituted triaminotriazines are prepared by heating a monochlorodiaminotriazine (in which one or both amino groups may be alkylated), or a dichloromonoaminotriazine (in which the amino group may be alkylated), or trichlorotriazine, with a drying oil amine in the presence of an alkaline agent.  Specified drying oil amines are those from soya bean, cotton seed, cod liver, croton, tung and linseed oils.  The second and third amino groups of the triazine may be alkylated, for example, by butyl, ethyl, octyl or tetradecyl groups, as in a 2 - alkylamino - 4 : 6 - dibutylamino - 1 : 3 : 5-triazine, where the 2-alkylamino is a drying oil amino substituent.  The reaction may be carried out in aqueous or organic solvent solution, such as alcohols, dioxane and "Cellosolves" (Registered Trade Mark).  In the examples (1 and 2), soya amines are heated with 2-chloro-4 : 6-diamino-1 : 3 : 5-triazine in presence of aqueous sodium hydroxide to give the 2-soya-amino compound.
