PROCESS FOR MAKING PULVERULENT AMMONIUM POLYPHOSPHATES STABLE TO HYDROLYSIS ABSTRACT OF THE DISCLOSURE The disclosure relates to a process for making a particulate agent stable to hydrolysis based on free- flowing, pulverulent ammonium polyphosphate by treating the ammonium polyphosphate with a thermosetting, arti- ficial resin being water-insoluble when cured. More spe- cifically, the disclosure provides for the ammonium poly- phosphate, an aliphatic alcohol as a diluent, and a mel- amine/formaldehyde-resin or phenol/formaldehyde-resin to be placed in an autoclave and intimately mixed at room temperature; for the mixture to be heated to a tempera- ture of about 80 to about 180°C and allowed to remain over a period of 15 to 240 minutes at that temperature and under the pressure corresponding to the vapor pressure of the diluent; for the diluent to be separated and for the product so obtained to be dried.
