METHOD OF OCTOGENE MODIFICATION Russian patent published in 2012 - IPC C06B21/00 C06B25/34 C06B45/22 

FIELD: chemistry.

SUBSTANCE: invention relates to explosives, particularly, to development of method of coating components of mixed solid-propellant rocket fuel. Modification of octogene is realized as follows: solution of polyethylene polyamine is prepared in methylene chloride and mixed at 20±5°C for 10-15 min. Octogene is added in tree steps at weight ratio of polyethylene polyamine and octogene to methylene chloride making 1:(5-7) for 15-20 min. Note here that octogene-to-polyethylene polyamine ratio makes 100:(0.03-0.05). Mixing is performed for 40-50 min at 20±5°C. Mix is cured at room temperature for 30 min, and dried at 70±5°C for 25-30 min.

EFFECT: better explosive, processing and strength characteristics.
