On heating, ammonium polyphosphate eliminates ammonia and water in two successive steps. The first (T= 165 280°C) involves a limited weight loss (ca. 3 "/o) and theJormation of some branched structures. The transition from one crystalline Jorm q[ ammonium polyphosphate to another, more stabh',Jorm,
