However, its utilization in tuning the degradability of polymers is underexplored, and there is no viable route to backbone-editable polyesters and polycarbonates with tunable lifecycles. In this work, we synthesized a series of backbone-editable polyesters and polycarbonate via ring-opening copolymerization (ROCOP) of 2-vinyloxirane (VIO) with anhydrides\/CO2. These polymers feature the specific structure necessary for [3,3]-sigmatropic oxo-rearrangements under a Pd catalyst, in which the terminal olefins can undergo rearrangement to trans internal ones and facilitate backbone modification. After optimizing the rearrangement conditions, we were able to rearrange the polyesters in satisfactory yields (55.2%\u201372.3%) without affecting the molecular weight. Notably, compared with the original polymers, the rearranged ones exhibit lower hydroboration\u2013oxidation reactivity and glass transition temperature, as well as much faster thermal and hydrolytic degradation profiles, providing a new strategy for the design of polymers with tunable properties and lifecycles.<\/jats:p>","DOI":"10.1093\/nsr\/nwaf534","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T13:08:54Z","timestamp":1764248934000},"source":"Crossref","is-referenced-by-count":3,"title":["Ring-opening
