✦ Synopsis

Addition of trimethylammonium perchlorate to potassium perchlorate (KP) catalyzes its thermal decomposition. However, although the additive sensitises KP-PU propellant decomposition, its combustion is desensitised. The observed effects have been explained in terms of the role played by the early formation of potassium chloride.

RESULTS AND DISCUSSION

The results of DTA studies of KP, MAP-3, and KP-MAP-3 mixtures are summarised in Table . The
