Abstract

Nonlinear dynamics procedures as well as spectral-correlation analysis are used for the acoustical response of consecutive physical-chemical stages of the organic self-propagating high-temperature synthesis. The transient nature of processes in the system studied is revealed. The study of changes in temporal and spatial dynamics of such systems allows driving the wave of the chemical reaction to make the solid phase "combustion" more efficient and produce condensed products with desired properties.
