SOME ASPECTS OF POLYMER PYROLYSIS

Pyrolysis is the important stage of polymer combustion. This process depends on molecular and submolecular structure of polymer as well as conditions of heat affect. It may be realized through the formation of nonvolatile carbonized product. The basic conception of the present work consists in the transformation of macromolecules into carbonized structure which realises by means of formation of the thermodynamically-advantageous intermediate compounds with a system of pi-conjugated unsaturated carbon bonds (acyclic or aromatic nature) and by their following conversion into condensed aromatic structures. It has been examined the correlation between the structure and properties of carbonized products and the flammability of polymers.
