The subject of the invention is a process for the manufacture of water-soluble condensation products of hydroxymethylphosphonium compounds and a 1,3,5-triazine characterised in that (a) 1 mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 0.1 mol, preferably 0.05 to 0.1 mol of optionally methylolated 1,3,5-triazine which is substituted by at least one primary amino group, at 40* to 120*C, optionally in the presence of formaldehyde or a formaldehyde-releasing agent and optionally in the presence of an inert organic solvent, the condensation is optionally thereafter continued at temperatures of 100* to 150*C and, if appropriate, free hydroxyl groups are etherified at least partially with at least one alkanol with 1 to 4 carbon atoms and, if appropriate, the salts of the condensation products are converted into the corresponding hydroxides. The condensation products are used for flameproofing organic fibre material, especially textiles. |
