摘要

This research explores the effects of structural and compositional changes occurring in polymer matrices during the initial stages of irradiation on the pyrolysis process focusing on structural and compositional changes within polymer matrices. Comparative analysis of irradiated and non-irradiated samples revealed. The results show that only a small fraction of radiation-induced radicals remains stable enough to participate in pyrolytic reactions, yet these long-lived radicals significantly alter the decomposition pathway. Their strong association with aromatic domains of polyethylene terephthalate highlights a distinct mechanism governing thermal degradation. The novelty of this work lies in demonstrating how irradiation history can fundamentally reshape pyrolytic reactions and waste recycling strategies.
