Title: Process for preparing hardenable aminoplasts
IPC: D06M15/423
Filed: 1963-08-02
Abstract: A process for the production of hardenable aminoplast products comprises reacting a bistriazinone of the general formula <FORM:1044306/C2/1> wherein n is 1 or 2, R is hydrogen or an alkyl radical having 1-4 C atoms and R1 is an alkylene radical of 1-4 C atoms, with two or more different aliphatic compounds each containing at least 8 carbon atoms and one group capable of reacting with amino groups, and further treating the product with 2.0 to 6.0 molar proportions of an aliphatic aldehyde.  The tertiary amine groups may be quaternized before the reaction with aldehyde, and the alkylol groups in the final product may be etherified, if desired, e.g. with a C1- 4 alkanol.  The bis-triaazinones may be prepared by condensing a di-alkylene triamine or trialkylene tetramine with dimethylolurea or an aldehyde and urea.  Suitable groups reactive towards amino groups are carboxylic acid halide and isocyanate groups, and also N-methylol amide, N-methylol urethane, chloromethyl ether, chlorocarbonic acid ester, carbamic acid chloride, carboxylic acid azide and carboxylic acid ester groups.  The aldehyde preferably contains 1-4 C atoms and may be e.g. formaldehyde, paraformaldehyde, acetaldehyde or glyoxal.  In examples stearic acid chloride is added to a solution of a bistriazinone prepared from diethylene triamine and dimethylol urea, followed by octadecyl isocyanate (Example 1) or oleic acid chloride (Example 2) to a total of about 1 mol. of reagent per mol. of bis-triazinone, followed by 4.4 mols. of formaldehyde, in 30% solution, per mol. of product.ALSO:A process for the production of hardenable aminoplast products comprises reacting a bistriazinone of the general formula <FORM:1044306/C3/1> wherein n is 1 or 2, R is hydrogen or a C1-4  alkyl group and R1 is a C1- 4 alkylene group, with two or more different aliphatic compounds containing at least 8 carbon atoms and one group capable of reacting with amino groups, and further treating the product with 2.0 to 6.0 molar proportions of an aliphatic aldehyde.

Uses.-Textile finishers, in conjunction with e.g. magnesium chloride, zinc nitrate, ammonium chloride or diglycolic acid hardeners, with or without e.g. dimethylol ethylene urea or polymethylol melamine.
