AP fits the definition of a monoprop in my book. Even if it only could release
its energy from high energy shock (which is *NOT* the case) it could still be a
monoprop. Any single monolithic molecular compound that has the potential to
release significant chemical energy without the requirement to react with
another substance and sustain self decomposition/energy liberation is a
monoprop in my book. Attached is a tiny pic from Solid Rocket Technology that
illustrates AP's burn rate characteristics as a sole ingredient as a comparison
to a typical APCP (at the time).

flame would spread, at 700 psi - not that it would auto-decompose.But 700 psi or 43 bars to have NH4ClO4 auto-decompose like a monoprop?Can't speak for Anthony, but he said it would act as a monoprop, ie
Matter of definition. The best way I can describe what a monoprop is, is
that it works because it relatively slowly auto-decomposes or catalytically
decomposes into gaseous products which next offer propulsion. H2O2 and N2H4
come to mind.
Detonating materials are considered propellants for guns maybe, not
monopropellants.
