Procedure

Melamine (63 g) was slowly added to a hot (80° C.) solution of hydrobromic acid (121.5 g) in water (1100 ml) and the solution allowed to cool. The crystals of melamine bromide were filtered off and dried in a vacuum oven at 120°. A yield of 72 g was obtained. The product was compounded into nylon 66 to give a concentration of 5% by weight of melamine bromide. A sample of the extrudate was ignited and was found to extinguish almost immediately the flame was removed.
