ABSTRACT:
The subject of the invention is a process for the manufacture of water-soluble condensation products of hydroxymethylphosphonium compounds and bicyclic dienes, characterized in that (a) one mol of a tetrakis-(hydroxymethyl)-phosphonium compound is condensed with (b) 0.02 to 1 mol, preferably 0.1 to 0.5 mol, of a 2,4,6,8,9-pentaazo-bicyclo-[3.3.1]-nona-2,6-diene of the formula ##STR1## or its salt, wherein R represents hydrogen, hydroxyl or an optionally substituted aliphatic, cycloaliphatic, aromatic or heterocyclic radical; at 40.degree. to 120.degree. 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.degree. to 150.degree. 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 fiber material, especially textiles.
