Аннотация: The ability of ionizing radiation to cleave bonds between monomer units is enhanced by heating, and can be used in practice to create radiation-thermal technologies for recycling polymer waste. The combination of pyrolysis and radiolysis leads to a positive effect by reducing the depolymerization temperature of plastics and the amount of pyrolytic waste, as well as by increasing the yield of liquid products and improving degradation control. Radiation-thermal treatment is suitable for converting individual plastics and inseparable compositions into fuel, monomers and various chemicals. 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. A promising unique direction is the creation of a radiation-supported method of accelerated tests of degradability of plastics.
