ABSTRACT:
The subject of the invention is a process for the manufacture of water-soluble condensation products of hydroxymethyl-phosphonium compounds and dicyandiamide, characterised in that (a) 1 mol of a tetrakis-(hydroxymethyl)phosphonium compound is condensed with (b) 0.02 to 0.2 mol, preferably 0.05 to 0.15 mol, of an optionally methylolated dicyandiamide at 40.degree. to 120.degree.C, optionally in the presence of formaldehyde or a formaldehyde-donating agent, and an inert organic solvent, and optionally subsequently further condensed at temperature of 100.degree. to 150.degree.C, and if appropriate free hydroxyl groups are at least partially etherified 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.
