摘要：

Crystalline ammonium polyphosphates with a chain length greater than 50 were characterized for the first time. Control of the ammonia vapor pressure is the key to producing these compounds at elevated temperatures. Five forms were identified. Single crystals of forms II, IV, and V were isolated and their cell parameters determined. The long-chain crystalline ammonium polyphosphates are quite insoluble in cold water and show a slower degradation rate than Graham's salt. © 1969, American Chemical Society. All rights reserved.
