Polyesters including poly(ethylene terephthalate) (PET) are one of the most prevalent polymers worldwide due to their attractive properties. However, most of them are primarily derived from fossil resources and essentially non-degradable, which raises sustainability concerns. A range of degradable polymers have been developed as more sustainable alternatives, however, limitations of practical degradability and scalability have hindered their viability. Here, we designed aromatic polyesters with excellent degradability as well as competitive properties from bio-based resources. These aromatic polyesters were miscible with PET while most polymer pairs are immiscible due to thermodynamic reasons; this results in tailoring PET properties in cost-effective and sustainable ways. Furthermore, salicylates moieties, the key structure for facile degradations, have been incorporated into commodity polymers by direct transesterification approaches. |
