Pyrolysis is the important stage of polymer combustion. This process d
epends on molecular and submolecular structure of polymer as well as c
onditions of heat affect. It may be realized through the formation of
nonvolatile carbonized product. The basic conception of the present wo
rk consists in the transformation of macromolecules into carbonized st
ructure which realises by means of formation of the thermodynamically-
advantageous intermediate compounds with a system of pi-conjugated uns
aturated carbon bonds (acyclic or aromatic nature) and by their follow
ing conversion into condensed aromatic structures. It has been examine
d the correlation between the structure and properties of carbonized p
roducts and the flammability of polymers.
