The Effect of Napster on Recorded Music Sales: Evidence from the Consumer Expenditure Survey

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 DEG to 120 DEG 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 DEG to 150 DEG 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.
