The ability of ionizing radiation to split bonds between monomeric units is enhanced by heating and can be used in practice to create radiation-thermal technologies for the transformation of natural polymers into valuable low molecular weight products, including monomers, solvents, fuels, etc. Irradiation of cellulose, chitin, and lignin at pre-pyrolysis temperatures initiates their direct chain disassembly into furans, pyridines, imidols, and phenols, recognized as excellent building blocks in chemical synthesis. The combination of pyrolysis and radiolysis leads to a positive effect by reducing the temperature of polymer degradation and the amount of pyrolytic waste, as well as by increasing the yield of liquid products and enhancing the controllability of degradation. High-temperature radiolysis is capable of converting plant polymers into monomer stabilizers and monocyclic building blocks for the synthesis of green plastics, and can also serve as an alternative (non-petroleum) route for the production of conventional monomers.
