Аннотация:A comparative study of two processes was carried out: frontal polymerization of 1,4-
diethynylbenzene, proceeding as a result of high-temperature initiation under increased
nitrogen pressure (P = 2–6 MPa), and ammonium perchlorate burning in the same conditions.
It was shown that the linear rate of thermal transformations of 1,4-diethynylbenzene is close to
the linear burning rate of the energetically saturated compound. The structure of the carbon
material obtained as a result of thermal transformations of 1,4-diethynylbenzene was
investigated using elemental analysis, Raman spectroscopy and scanning electron microscopy.
