Polymerization of composite binders in a low-temperature combustion wave

Processes in the heat wave that accompanies the self-propagating low-temperature conversion (combustion) of an energetic component in systems containing an inert (inorganic) and an energy-releasing filler, as well as an uncured binder, were experimentally studied. The temperature arrangement of the heat wave upon its propagation through a composite was studied by the microthermocouple technique. Using an oligoisocyanurate based on the 1,6-hexamethylenediisocyanate trimer as an example, it was shown that conditions at which its cyclopolymerization occurs without noticeable thermal degradation of the polymer formed could he provided during the process. The progress of the curing and network formation was monitored by measuring the IR spectra and the mechanical properties of the composites. The possibility of using the process to manufacture porous composites based on other polymer binders is discussed.
