Abstract:This article reports a potential high-value reuse pathway for a depolymerized vitrimer matrix from abandoned composites. A series of polyethylene terephthalate (PET)-based copolymers containing various amounts of added vitrimer as the toughness modifier were synthesized by melt polymerization. The thermal, mechanical, and crystallization behaviors of the synthesized copolymers were determined, indicating all samples presented excellent thermal stability at Td−5% above 390 ℃. The differential scanning calorimet… Show more
